For the nutrient commonly called sodium, see, "Natrium" redirects here. In a liquid state, sodium is completely miscible with lead. You may know salt best as the white crystals that bring out the flavor in your roasted potatoes. About 90% of the sodium we eat is in the form of sodium chloride. The other 60 percent is another mineral, chloride. After a while, it glowed a bright yellow and showed a strong sodium line that disappeared only after 10 minutes. These are still made of salt, but they substitute a portion with potassium chloride. [32], Because of its importance in human health, salt has long been an important commodity, as shown by the English word salary, which derives from salarium, the wafers of salt sometimes given to Roman soldiers along with their other wages. [73] In this case, the pyrophoricity of potassium requires extra precautions to prevent and detect leaks. That said, when it comes to health and nutrition, it’s important to pay attention to both salt and sodium. Halophytes have adapted to be able to flourish in sodium rich environments. Sodium chloride is extensively used for anti-icing and de-icing and as a preservative; examples of the uses of sodium bicarbonate include baking, as a raising agent, and sodablasting. And while we generally think of the salt shaker as the only source of sodium, sodium also exists in most whole foods , from cantaloupe to eggs. The main aqueous species are the aquo complexes [Na(H2O)n]+, where n = 4–8; with n = 6 indicated from X-ray diffraction data and computer simulations. [70] The high boiling point of sodium allows the reactor to operate at ambient (normal) pressure,[70] but the drawbacks include its opacity, which hinders visual maintenance, and its explosive properties. Sodium hydroxide is neutralized with hydrochloric acid to produce the soluble salt sodium chloride in solution. An exception is sodium bismuthate (NaBiO3). When the concentration of sodium increases, the production of renin decreases, and the sodium concentration returns to normal. It is found in many minerals, some very soluble, such as halite and natron, others much less soluble, such as amphibole and zeolite. To keep a lid on sodium, fill your diet with more freshly-prepared foods that are naturally low in sodium such as fruits and vegetables, as well as whole grains and proteins without added salt. It is a soft, silvery-white, highly reactive metal. [77] Other sources of sodium are its natural occurrence in food and such food additives as monosodium glutamate (MSG), sodium nitrite, sodium saccharin, baking soda (sodium bicarbonate), and sodium benzoate. In medieval Europe, a compound of sodium with the Latin name of sodanum was used as a headache remedy. [21] Because of the high solubility of its compounds, sodium salts are usually isolated as solids by evaporation or by precipitation with an organic antisolvent, such as ethanol; for example, only 0.35 g/L of sodium chloride will dissolve in ethanol. Sodium is most commonly found in food as salt (sodium chloride). [62] By itself or with potassium, sodium is a desiccant; it gives an intense blue coloration with benzophenone when the desiccate is dry. [63] In organic synthesis, sodium is used in various reactions such as the Birch reduction, and the sodium fusion test is conducted to qualitatively analyse compounds. Levels of 7 g per day or more in people with hypertension were associated with higher mortality and cardiovascular events, but this was not found to be true for people without hypertension. Sodium not only helps your body keep fluids in all the right places, but also aids in nerve conduction and helps your muscles work. This solution is then concentrated and crystallized to produce sodium chloride crystals. The American Heart Association goes even further, and says you'd be better off limiting your intake to 1,500 milligrams a day. [104], This article is about the chemical element. Many processed and prepared foods contain sodium. For other uses, see. Sodium is a metal and chloride is an anion of chlorine. From an everyday health perspective, it is not important to know the ins and outs of the chemistry, but it is important to realise that not all salt is sodium and not all sodium is in salt. [59] Sodium hydride is used as a base for various reactions (such as the aldol reaction) in organic chemistry, and as a reducing agent in inorganic chemistry. [41] Sodium's estimated oceanic abundance is 1.08×104 milligrams per liter. The introduction of the Hall–Héroult process for the production of aluminium by electrolysing a molten salt bath ended the need for large quantities of sodium. Then the amount of sodium in 3 grams of salt = 39.3% x 3 = 1.179 g or about 1200 mg. An easy way to calculate the amount of sodium in salt is to realize 39.3% of … Sodium also forms alloys with gold (NaAu2) and silver (NaAg2). [39], Sodium imparts an intense yellow color to flames. NaZn13 and NaCd2 are alloys of zinc and cadmium. [17] In compounds, sodium is usually ionically bonded to water and anions and is viewed as a hard Lewis acid. Her work has been featured on the Huffington Post, Diabetes Self-Management and Working Mother. [16] Metallic sodium was first produced commercially in the late 19th century[50] by carbothermal reduction of sodium carbonate at 1100 °C, as the first step of the Deville process for the production of aluminium:[51][52][53], The high demand for aluminium created the need for the production of sodium. [60], Metallic sodium is used mainly for the production of sodium borohydride, sodium azide, indigo, and triphenylphosphine. [17], Like all the alkali metals, sodium reacts exothermically with water. Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Salt is called sodium chloride for a reason: It's 40 percent sodium and 60 percent chlorine, and cutting out most of the sodium makes it, well, something that isn't salt. In a corner of our 60 m3 room farthest away from the apparatus, we exploded 3 mg of sodium chlorate with milk sugar while observing the nonluminous flame before the slit. As calcium is less electropositive than sodium, no calcium will be deposited at the cathode. © Copyright 2020 Hearst Communications, Inc. [16] Sodium is also used as an alloying metal, an anti-scaling agent,[61] and as a reducing agent for metals when other materials are ineffective. Sodium is most commonly eaten as a component of table salt, which is only partly sodium. Sodium is an alkali metal, being in group 1 of the periodic table. [23], Sodium content of samples is determined by atomic absorption spectrophotometry or by potentiometry using ion-selective electrodes. Reduction of blood pressure and sodium concentration in the kidney result in the production of renin, which in turn produces aldosterone and angiotensin, which stimulates the reabsorption of sodium back into the bloodstream. [80] The American Heart Association recommends no more than 1.5 g of sodium per day. Sodium is soluble in water and present in oceans and in stagnant bodies of water, in large quantities, counterbalanced by chloride. Atomic sodium has a very strong spectral line in the yellow-orange part of the spectrum (the same line as is used in sodium vapour street lights). The solutions contain the coordination complex (Na(NH3)6)+, with the positive charge counterbalanced by electrons as anions; cryptands permit the isolation of these complexes as crystalline solids. Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite.Salt is present in vast quantities in seawater, where it is the main mineral constituent.The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%. But those crystals are actually minerals made up of the two compounds sodium and chloride, with 40 percent from sodium and 60 percent from chloride. Sodium is a substance that affects blood pressure and is the main ingredient in salt. An effective extinguishing agent for sodium fires is Met-L-X. “Salt substitutes can be a healthy alternative for some people because potassium is an important mineral that helps lower blood pressure,” says dietitian Maxine Smith, RD, LD. They collect leaking sodium into a leak-recovery tank where it is isolated from oxygen. In the case of massive (non-molten) pieces of sodium, the reaction with oxygen eventually becomes slow due to formation of a protective layer. [48] Sodium has even been detected in the atmospheres of some extrasolar planets via transit spectroscopy. For most people, packaged foods, fast food and ready-to-go meals constitute more than 75 percent of their sodium intake. A related process based on the reduction of sodium hydroxide was developed in 1886. Sodium forms complexes with crown ethers, cryptands and other ligands. At the grocery store, keep an eye out for foods labeled "low sodium." Common salt is sodium chloride, which is about 40% sodium and 60% chloride by weight. [36] The chemical abbreviation for sodium was first published in 1814 by Jöns Jakob Berzelius in his system of atomic symbols,[37][38] and is an abbreviation of the element's New Latin name natrium, which refers to the Egyptian natron,[33] a natural mineral salt mainly consisting of hydrated sodium carbonate. [75], In humans, sodium is an essential mineral that regulates blood volume, blood pressure, osmotic equilibrium and pH. A once-common use was the making of tetraethyllead and titanium metal; because of the move away from TEL and new titanium production methods, the production of sodium declined after 1970. However, sodium exposed to air and ignited or reaching autoignition (reported to occur when a molten pool of sodium reaches about 290 °C)[101] displays a relatively mild fire. [92] In others, it substitutes for potassium in several roles, such as maintaining turgor pressure and aiding in the opening and closing of stomata. A teaspoon of table salt has about 2,300 mg of sodium, but a teaspoon of sea salt or kosher salt may have less sodium simply because fewer crystals fit on the spoon. Sodium is not salt, rather it is an element that makes up salt. What Is Considered Low Sodium on a Nutrition Panel? There are several methods to make sodium-lead alloys. One is to melt them together and another is to deposit sodium electrolytically on molten lead cathodes. When dining out, ask for your food to be made without salt. [99][100] Sodium spontaneously explodes in the presence of water due to the formation of hydrogen (highly explosive) and sodium hydroxide (which dissolves in the water, liberating more surface). Table salt is a combination of two minerals — about 40% sodium and 60% chloride. It takes 1.875 grams of salt to get 750 miligrams (mg) of sodium. Table salt consists of sodium and chloride, so its chemical name is sodium chloride. [34][35] In 1809, the German physicist and chemist Ludwig Wilhelm Gilbert proposed the names Natronium for Humphry Davy's "sodium" and Kalium for Davy's "potassium". 1 mole of NaCl = 23 + 35.5 g = 58.5 grams per mole. Because of this, a Tolerable Upper intake Level (UL) has not been established; a UL is the maximum daily intake unlikely to cause harmful effects on health. [95], Sodium forms flammable hydrogen and caustic sodium hydroxide on contact with water;[98] ingestion and contact with moisture on skin, eyes or mucous membranes can cause severe burns. High blood pressure increases your risk of heart disease and stroke. In fact, according to the U.S. Food and Drug Administration (FDA), low-sodium salt isn't even food, as food-grade salt is required to consist of at least 97.5 percent sodium chloride. [94] In response, some plants have developed mechanisms to limit sodium uptake in the roots, to store it in cell vacuoles, and restrict salt transport from roots to leaves;[95] excess sodium may also be stored in old plant tissue, limiting the damage to new growth. [42] Because of its high reactivity, it is never found as a pure element. [19], Sodium tends to form water-soluble compounds, such as halides, sulfates, nitrates, carboxylates and carbonates. Common brands include Lo Salt, Morton Lite Salt, Tata, Saxa So-Low, and Himalania reduced sodium pink salt. While salt is made up of mostly chloride, it’s still considered a high-sodium item. It is the sodium part of salt that is necessary to maintain water balance in body tissues. NaPb3, NaPb, Na9Pb4, Na5Pb2, and Na15Pb4 are some of the known sodium-lead alloys. [51], Sodium is now produced commercially through the electrolysis of molten sodium chloride, based on a process patented in 1924. Here are the approximate amounts of sodium in a given amount of salt: 1/4 teaspoon salt = 575 mg sodium 1/2 teaspoon salt = 1,150 mg sodium [25] For example, 15-crown-5 has a high affinity for sodium because the cavity size of 15-crown-5 is 1.7–2.2 Å, which is enough to fit the sodium ion (1.9 Å). Salt (also known by its chemical name, sodium chloride) is a crystal-like compound that is abundant in nature. The reaction produces caustic soda (sodium hydroxide) and flammable hydrogen gas. [18], Most soaps are sodium salts of fatty acids. [100] Other effective agents include Lith-X, which has graphite powder and an organophosphate flame retardant, and dry sand. These conditions may be caused by genetic factors, ageing, or prolonged vomiting or diarrhea. 750 miligrams of sodium in salt is about 0.3281 teaspoons. Humphry Davy (1809) "Ueber einige neue Erscheinungen chemischer Veränderungen, welche durch die Electricität bewirkt werden; insbesondere über die Zersetzung der feuerbeständigen Alkalien, die Darstellung der neuen Körper, welche ihre Basen ausmachen, und die Natur der Alkalien überhaupt" (On some new phenomena of chemical changes that are achieved by electricity; particularly the decomposition of flame-resistant alkalis [i.e., alkalies that cannot be reduced to their base metals by flames], the preparation of new substances that constitute their [metallic] bases, and the nature of alkalies generally), sixth most abundant element in the Earth's crust, "Atomic weights of the elements 2013 (IUPAC Technical Report)", Magnetic susceptibility of the elements and inorganic compounds, "Determination of Sodium with Ion-Selective Electrodes", "On some new phenomena of chemical changes produced by electricity, particularly the decomposition of the fixed alkalies, and the exhibition of the new substances which constitute their bases; and on the general nature of alkaline bodies", "Chemische Analyse durch Spectralbeobachtungen", "How surface composition and meteoroid impacts mediate sodium and potassium in the lunar exosphere", 10.1002/0471238961.1915040912051311.a01.pub3, "Los Alamos National Laboratory – Sodium", American Society for Testing and Materials, "Laser Development for Sodium Laser Guide Stars at ESO", "Über das Zustandsdiagramm der Kalium-Natriumlegierungen", "Sodium and Potassium Quick Health Facts", U.S. Department of Health and Human Services, "Impact of dietary and lifestyle factors on the prevalence of hypertension in Western populations", "Global burden of blood-pressure-related disease, 2001", "Use the Nutrition Facts Label to Reduce Your Intake of Sodium in Your Diet", "Manganese Nutrition and Photosynthesis in NAD-malic enzyme C4 plants PhD dissertation", Hazard Rating Information for NFPA Fire Diamonds, http://terpconnect.umd.edu/~pbs/2013-An-et-al-FSJ.pdf, Etymology of "natrium" – source of symbol Na, The Wooden Periodic Table Table's Entry on Sodium, https://en.wikipedia.org/w/index.php?title=Sodium&oldid=995044991, Biology and pharmacology of chemical elements, Short description is different from Wikidata, Wikipedia pages semi-protected against vandalism, Articles with unsourced statements from June 2020, Creative Commons Attribution-ShareAlike License, This page was last edited on 18 December 2020, at 22:51. [93] Excess sodium in the soil can limit the uptake of water by decreasing the water potential, which may result in plant wilting; excess concentrations in the cytoplasm can lead to enzyme inhibition, which in turn causes necrosis and chlorosis. [78], The U.S. Institute of Medicine set its Tolerable Upper Intake Level for sodium at 2.3 grams per day,[79] but the average person in the United States consumes 3.4 grams per day. Sodium amide is a strong base. So, 5 grams of salt is equal to 2000mg of sodium, both of which are contained in one teaspoon of salt. [85][86]), One study found that people with or without hypertension who excreted less than 3 grams of sodium per day in their urine (and therefore were taking in less than 3 g/d) had a higher risk of death, stroke, or heart attack than those excreting 4 to 5 grams per day. [90], Unusually low or high sodium levels in humans are recognized in medicine as hyponatremia and hypernatremia. [102] Fire extinguishers based on water accelerate sodium fires; those based on carbon dioxide and bromochlorodifluoromethane should not be used on sodium fire. USDA, Agricultural Research Service, Nutrient Data Laboratory. [100] Metal fires are Class D, but not all Class D extinguishers are workable with sodium. While sodium is a component of salt, they are not one in the same. [64] Sodium reacts with alcohol and gives alkoxides, and when sodium is dissolved in ammonia solution, it can be used to reduce alkynes to trans-alkenes. Some varieties of sea salt claim to have less sodium than table salt. Salt has … Some well-known derivatives include sodium cyclopentadienide (NaC5H5) and trityl sodium ((C6H5)3CNa). [26][27] Cryptands, like crown ethers and other ionophores, also have a high affinity for the sodium ion; derivatives of the alkalide Na− are obtainable[28] by the addition of cryptands to solutions of sodium in ammonia via disproportionation. Find resources and tips for reducing the amount in your diet while keeping the flavor. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and rock salt(NaCl). This calculator converts the sodium listed on food products into grams of salt or vice versa. As early as 1860, Kirchhoff and Bunsen noted the high sensitivity of a sodium flame test, and stated in Annalen der Physik und Chemie:[40]. [74] Another heat transfer application is poppet valves in high-performance internal combustion engines; the valve stems are partially filled with sodium and work as a heat pipe to cool the valves. Sodium amide (NaNH2) is a greyish-white powder with a slight ammonia odor that oxidizing agents, hydrated salts, acids and a wide variety of other materials.The chemical formula of sodium amide is NaNH2, and its molar mass is 39.01 g/mol. [20], Direct precipitation of sodium salts from aqueous solutions is rare because sodium salts typically have a high affinity for water. A small amount of sodium is required by the body as it plays an essential role in keeping the fluids and electrolytes in our bodies balanced. Fraunhofer named it the 'D' line, although it is now known to actually be a group of closely spaced lines split by a fine and hyperfine structure. Sodium and mercury form NaHg, NaHg4, NaHg2, Na3Hg2, and Na3Hg. [91], In C4 plants, sodium is a micronutrient that aids metabolism, specifically in regeneration of phosphoenolpyruvate and synthesis of chlorophyll. Sodium-calcium alloys are by-products of the electrolytic production of sodium from a binary salt mixture of NaCl-CaCl2 and ternary mixture NaCl-CaCl2-BaCl2. It is an excellent thermal and electrical conductor. Jill Corleone is a registered dietitian and health coach who has been writing and sharing her love of food, nutrition and health with anyone who'll listen for almost 20 years. Consider that a single teaspoon of table salt, which is a combination of sodium and chloride, has 2,325 milligrams (mg) of sodium — more than the daily amount recommended in the Dietary Approaches to Stop Hypertension (DASH) diet. [33] Although sodium, sometimes called soda, had long been recognized in compounds, the metal itself was not isolated until 1807 by Sir Humphry Davy through the electrolysis of sodium hydroxide. USDA FoodData Central . [30] Sodium naphthalenide, Na+[C10H8•]−, a strong reducing agent, forms upon mixing Na and naphthalene in ethereal solutions. Many other stars appear to have a sodium absorption line, but this is actually caused by gas in the foreground interstellar medium. [104] Pool-type sodium fires are prevented using diverse design measures called catch pan systems. Learn more about salt and sodium in your diet and how it affects your health. Now let’s look at table salt, which is a combination of sodium and chloride. Most of the world’s salt is harvested from salt mines (from sea beds that dried up long ago) or by evaporating seawater and other mineral-rich waters. Even if certain food or drink does not contain any salt, sodium can be present in these. This is accomplished in all animals by Na+/K+-ATPase, an active transporter pumping ions against the gradient, and sodium/potassium channels. Sodium and potassium form KNa2 and NaK. [87] The US FDA states that adults with hypertension and prehypertension should reduce daily intake to 1.5 g.[86], The renin–angiotensin system regulates the amount of fluid and sodium concentration in the body. And it's not just table salt you have to worry about. While sodium is a component of salt, they are not one in the same. [22] Crown ethers, like 15-crown-5, may be used as a phase-transfer catalyst. [72] If a reactor needs to be shut down frequently, NaK is used; because NaK is a liquid at room temperature, the coolant does not solidify in the pipes. The Earth's crust contains 2.27% sodium, making it the seventh most abundant element on Earth and the fifth most abundant metal, behind aluminium, iron, calcium, and magnesium and ahead of potassium. Natron historically had several important industrial and household uses, later eclipsed by other sodium compounds. This appears as an absorption line in many types of stars, including the Sun. Salt is also called sodium chloride (NaCl). The two can be distinguished via high-resolution spectroscopy, because interstellar lines are much narrower than those broadened by stellar rotation. [31], Sodium forms alloys with many metals, such as potassium, calcium, lead, and the group 11 and 12 elements. Sodium is a chemical element with the symbol Na (from Latin "natrium") and atomic number 11. 10H2O). [54][55] This is done in a Downs cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 °C. [82], Hypertension causes 7.6 million premature deaths worldwide each year. [103] Sodium fires are prevented in nuclear reactors by isolating sodium from oxygen by surrounding sodium pipes with inert gas. Some comets have a sodium tail,[47] which was first detected in observations of Comet Hale-Bopp in 1997. Table salt, or sodium chloride (NaCl), is approximately 40% sodium and 60% chloride by weight. When burned in air, it forms primarily sodium peroxide with some sodium oxide. In fact, sodium is a mineral found naturally in almost all foods. The U.S. Dietary Reference Intakes state that there is not enough evidence to establish a Recommended Dietary Allowance or a toxic level for sodium (aside from chronic disease risk). In stars, it is seen in any whose surfaces are cool enough for sodium to exist in atomic form (rather than ionised). There's a difference between salt and sodium, and only one can be bad for you. Sodium is a mineral, and one of the chemical elements found in salt. Sodium bicarbonate is better known as baking soda. It consists of 40% sodium and 60% chloride, by weight. Table salt contains 40% sodium and 60% chloride. Note the free element is not used as a scaling agent, ions in the water are exchanged for sodium ions. It’s one of your body’s electrolytes, which are minerals that create electrically charged ions. Because of the high polarity of the C-Na bonds, they behave like sources of carbanions (salts with organic anions). From the weight of the sodium salt and the volume of air in the room, we easily calculate that one part by weight of air could not contain more than 1/20 millionth weight of sodium. Sodium is 23/58.5 x 100% = 39.3% of salt is sodium. [24], Like the other alkali metals, sodium dissolves in ammonia and some amines to give deeply colored solutions; evaporation of these solutions leaves a shiny film of metallic sodium. But you may wonder: Aren’t they the same thing? Some also include glutamic acid, lysine, and magnesium carbonate to enhance flavor. The name sodium is thought to originate from the Arabic suda, meaning headache, as the headache-alleviating properties of sodium carbonate or soda were well known in early times. [29], Many organosodium compounds have been prepared. [49], Employed only in rather specialized applications, only about 100,000 tonnes of metallic sodium are produced annually. SALT (wikipedia) In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. [88] The sodium ion (Na+) is an important electrolyte in neuron function, and in osmoregulation between cells and the extracellular fluid. The line was first studied in 1814 by Joseph von Fraunhofer during his investigation of the lines in the solar spectrum, now known as the Fraunhofer lines. The minimum physiological requirement for sodium is estimated to range from about 120 milligrams per day in newborns to 500 milligrams per day over the age of 10. Ordinary table salt is only 40 percent sodium. Its only stable isotope is Na. Group 12 metals (zinc, cadmium and mercury) are known to make alloys with sodium. Guidelines for Adequate Intakes (AI) of sodium were established based on the lowest levels of sodium … NaK is 40–90% potassium and it is liquid at ambient temperature. More than 75% of the sodium we eat comes from processed foods like canned soups, lunch meats and frozen dinners. [81], Studies have found that lowering sodium intake by 2 g per day tends to lower systolic blood pressure by about two to four mm Hg. [56] This method is less expensive than the previous Castner process (the electrolysis of sodium hydroxide). [65][66] Lasers emitting light at the sodium D line are used to create artificial laser guide stars that assist in the adaptive optics for land-based visible-light telescopes. [44], Sodium has also been detected in numerous Solar System environments, including Mercury's atmosphere,[45] the exosphere of the Moon,[46] and numerous other bodies. When it comes to diet and nutrition, the 2015 to 2020 Dietary Guidelines for Americans recommend you limit your daily intake of sodium to 2,300 milligrams a day. This corresponds to stars of roughly F-type and cooler. Calcium is only partially miscible with sodium. American Heart Association: Sodium and Your Health, Harvard Health Publishing: Harvard Medical School: Take it With a Grain of Salt, Centers for Disease Control and Prevention: Salt, How to Stabilize High Blood Sodium Levels. Find out what is sodium, how it differs from salt and how much your body needs. [67], Liquid sodium is used as a heat transfer fluid in some types of nuclear reactors[69] because it has the high thermal conductivity and low neutron absorption cross section required to achieve a high neutron flux in the reactor. [58], Though metallic sodium has some important uses, the major applications for sodium use compounds; millions of tons of sodium chloride, hydroxide, and carbonate are produced annually. The kicker is, you only need about 200 milligrams of sodium a day for normal body functions, and most Americans consume closer to 3,400 milligrams. When your blood has too much sodium, your body shifts more fluid into the bloodstream to dilute it. One teaspoon of table salt contains 2,300 milligrams of sodium. While salt is high in sodium, it’s probably not the primary source in your diet. If a recipe calls for one teaspoon of salt and serves 4 people, you're getting one-quarter of a teaspoon of salt from it or around 500mg sodium per serve. It is a salt composed of the sodium cation and the azanide anion. Alfred Klemm, Gabriele Hartmann, Ludwig Lange, "Sodium and Sodium Alloys" in Ullmann's Encyclopedia of Industrial Chemistry 2005, Wiley-VCH, Weinheim. [43], The strength of the D line means it has been detected in many other astronomical environments. Sodium plasma ("vapor") lamps are often used for street lighting in cities, shedding light that ranges from yellow-orange to peach as the pressure increases. [89] Sodium is the most prevalent metallic ion in extracellular fluid. [83] (Note that salt contains about 39.3% sodium[84]—the rest being chlorine and trace chemicals; thus, 2.3 g sodium is about 5.9 g, or 5.3 ml, of salt—about one US teaspoon. [57], The market for sodium is volatile due to the difficulty in its storage and shipping; it must be stored under a dry inert gas atmosphere or anhydrous mineral oil to prevent the formation of a surface layer of sodium oxide or sodium superoxide. The insolubility of certain sodium minerals such as cryolite and feldspar arises from their polymeric anions, which in the case of feldspar is a polysilicate.
