Megatons of these compounds are produced annually. [114], There are thousands of uses of various potassium compounds. [119] The ternary alloy of 12% Na, 47% K and 41% Cs has the lowest melting point of â78 °C of any metallic compound. As of now, Germanic countries use the word "kalium", and English speaking countries use the word "potassium". Potassium was isolated in 1807 by Sir Humphry Davy, who obtained it through the electrolysis of very dry molten caustic potash (KOH, potassium hydroxide). [115][116], Another example is potassium cobaltinitrite, K3[Co(NO2)6], which is used as artist's pigment under the name of Aureolin or Cobalt Yellow. eds. [123], Because potassium reacts with water vapor in the air, it is usually stored under anhydrous mineral oil or kerosene. Hebrew and Egyptian words for it had the consonants n-t-r, indicating likely cognation in the Greek nitron, which was Latinised to nitrum or nitrium. The symbol is the short form or abbreviated name of the element. You can reference the WebElements periodic table as follows:"WebElements, https://www.webelements.com, accessed December 2020. Because its density is 0.89 g/cm3, burning potassium floats in water that exposes it to atmospheric oxygen. Copyright 1993-2020 Mark Winter [ The University of Sheffield and WebElements Ltd, UK]. It is widely used in respiration systems in mines, submarines and spacecraft as it takes less volume than the gaseous oxygen.

[124], Ingestion of large amounts of potassium compounds can lead to hyperkalemia, strongly influencing the cardiovascular system. daytime for humans, nighttime for rodents) independent of the presence, amount, or absence of potassium ingestion. So, in 1807, while he was in Royal Institution, London, he took Potash or Potassium Hydroxide ⦠Potassium's chemical symbol comes from the Latin word for alkali, kalium. Dalton also noted that in series of compounds, the ratios of the masses of the second element that combine with a given weight of the first element can be reduced to small whole numbers (the law of multiple proportions). Atomic number (number of protons in the nucleus): 19 2. Well before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. Potassium is an essential nutrient that the body requires for a wide range of functions, including keeping the heart beating. Most health authorities agree that getting 3,500â4,700 mg of potassium daily appears to ⦠Potassium and sodium cations influence fluid distribution between intracellular and extracellular compartments by, This page was last edited on 27 November 2020, at 14:19. Potassium nitrate, because of its early and global use and production, has many names. Ancient Minerals Magnesium Oil takes its name from its ancient and pristine source, the ancient Zechstein Sea, a geological formation in Northern Europe from the Late Permian Era. After prolonged storage in air dangerous shock-sensitive peroxides can form on the metal and under the lid of the container, and can detonate upon opening. Since the body canât produce potassium, it has to come from food. [125][126] Potassium chloride is used in the United States for lethal injection executions. Many element's symbols are derrived from their ancient names. (1997). The principal source of potassium â potash â is mined in Canada, Russia, Belarus, Kazakhstan, Germany, Israel, United States, Jordan, and other places around the world. The K symbol for the element comes from the Latin word "kalium", which means potash. Potassium was the first metal isolated by electrolysis. It can also be used in reactive distillation. [112] Potassium permanganate (KMnO4) is an oxidizing, bleaching and purification substance and is used for production of saccharin. Thence Old French had niter and Middle English nitre. Get an answer to your question âA sample of ancient granite crust is dated using potassium-40.Scientists find that 50% of the potassium-40 has decayed to form argon-40. Potassium citrate may also be used for other purposes other than those listed in this medication guide. However, the name alum and other names applied to this substance â like misy , sory , chalcanthum , and atramentum sutorium â were often applied to other products with vaguely similar properties or uses, such as iron sulfate or "green vitriol". It is also used to bleach textiles and straw, and in the tanning of leathers. Potash (/ Ë p É t æ Ê /) includes various mined and manufactured salts that contain potassium in water-soluble form. Some Class D dry powder extinguishers designed for metal fires are also effective. How to make potassium nitrate at home with instant cold packs and "sodium-free" salt. The list below gives the element name, symbol, old name & name source for these oddly symboled elements. From the English word potash. "Sodium-free" salt is actually potassium chloride. This was further evidence for atoms. Itâs necessary for the heart, kidneys, and other organs to work normally. Potassium collected at the cathode. For example, Pb is the symbol for lead. It is an ancient term used to label the element and has its roots in the term âalkali.â Like the other elements in the first column, potassium is an associate of the alkali group with caesium and sodium. Potassium is a mineral and an electrolyte, which conducts electrical impulses throughout the body. Each element has a chemical symbol that is unique to ⦠Short answer: Potassium was called Potassium (and Sodium Sodium) by Humphry Davy, who first isolated both; it was then renamed Kalium in Germanic countries because of a previous naming proposal by Klaproth, who was the first to show that potassium carbonate and sodium carbonate were different. Small variations in ranges may be possible depending on the laboratory. A potassium level higher than 5.5 mmol/L is critically high, and a potassium level over 6 mmol/L can be life-threatening. ), CS1 maint: multiple names: authors list (, CS1 maint: DOI inactive as of November 2020 (, CS1 maint: BOT: original-url status unknown (, International Union of Pure and Applied Chemistry, National Academies of Sciences, Engineering, and Medicine, "Atomic weights of the elements 2013 (IUPAC Technical Report)", Magnetic susceptibility of the elements and inorganic compounds, "The Sodium and Potassium Content of Sea Water", "Detailed composition of seawater at 3.5% salinity", "On some new phenomena of chemical changes produced by electricity, in particular the decomposition of the fixed alkalies, and the exhibition of the new substances that constitute their bases; and on the general nature of alkaline bodies", "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", 19. Potassium, the most abundant intracellular cation, is an essential nutrient that is naturally present in many foods and available as a dietary supplement. One is active and pumps sodium out of, and potassium into, the cell. [109], Potassium hydroxide KOH is a strong base, which is used in industry to neutralize strong and weak acids, to control pH and to manufacture potassium salts. But in May 2016, the Nutrition Facts rules were changed, and potassium will now be listed. Eventually a distinction was made. Due to the electrostatic and chemical properties, The reactive negative-feedback system refers to the system that induces renal secretion of potassium in response to a rise in the plasma potassium (potassium ingestion, shift out of cells, or intravenous infusion. The other is passive and allows potassium to leak out of the cell. Potassium chlorate (KClO3) is added to matches and explosives. The symbol used by Dalton for potassium is shown below. The name of potash originated from the pots which were used in the process and the ash-like residue that is scraped from their bottom. For the use of potassium as a medication, see, Potassium pearls (in paraffin oil, ~5 mm each), Renal filtration, reabsorption, and excretion. Brand names: Klor-Con, KCl, Klor-Con M20, K-Dur Drug class(es): minerals and electrolytes Potassium chloride systemic is used in the treatment of:. Potassium bisulfite (KHSO3) is used as a food preservative, for example in wine and beer-making (but not in meats). From the French, charbone, which in turn came from Latin carbÅ, which means "charcoal" and is related to carbÅn, which means "a coal". Potassium bromide (KBr) was formerly used as a sedative and in photography. A. McCleverty and T. J. Meyer (eds. Nitrogen, argon, sodium chloride (table salt), sodium carbonate (soda ash), and silicon dioxide (sand) are effective if they are dry. [102] In 2005, about 93% of world potassium production was consumed by the fertilizer industry. Klaproth, M. (1797) "Nouvelles données relatives à l'histoire naturelle de l'alcali végétal" (New data regarding the natural history of the vegetable alkali). These names can be researched individually. Scientists have adopted certain conventions regarding the chemical symbols for various elements. ), The reactive feed-forward system refers to an incompletely understood system that induces renal potassium secretion in response to potassium ingestion prior to any rise in the plasma potassium. [118], An alloy of sodium and potassium, NaK is a liquid used as a heat-transfer medium and a desiccant for producing dry and air-free solvents. [105] It is given by slow injection into a vein or by mouth. It is mediated by a, The ion transport system moves potassium across the cell membrane using two mechanisms. Data sources include IBM Watson Micromedex (updated 2 Nov 2020), Cerner Multum⢠(updated 2 Nov 2020), ⦠Dalton's theory of atoms was published by Thomas Thomson in the 3rd edition of his System of Chemistry in 1807 and in a paper about strontium oxalates published in the Philosophical Transactions. [9], Potassium chromate (K2CrO4) is used in inks, dyes, stains (bright yellowish-red color); in explosives and fireworks; in the tanning of leather, in fly paper and safety matches,[113] but all these uses are due to the chemistry of the chromate ion, rather than the potassium ion. Density: 0.89 grams per cubic centimeter 5. [See History of Chemistry, Sir Edward Thorpe, volume 1, Watts & Co, London, 1914.]. Electrolytes assist in essential body functions. 3. For a long time, potassium wasnât listed on the Nutrition Facts food labels of packaged food items. Potassium is a mineral that is found in many foods and is needed for several functions of your body, especially the beating of your heart. resting cellular-membrane potential and the propagation of action potentials in neuronal, muscular, and cardiac tissue. Dalton published these ideas himself in the following year in the New System of Chemical Philosophy. Finely powdered potassium ignites in air at room temperature. (The German and Dutch names, "Kohlenstoff" and "koolstof", respectively, both literally mean "coal matter".) It's ancient Latin name was "plumbum". Many common fire extinguishing agents, including water, either are ineffective or make a potassium fire worse. WebElements: THE periodic table on the WWW [www.webelements.com] Potassium bromate (KBrO3) is a strong oxidizer (E924), used to improve dough strength and rise height. Phase at room temperature: Solid 6. [110][111], Potassium nitrate (KNO3) or saltpeter is obtained from natural sources such as guano and evaporites or manufactured via the Haber process; it is the oxidant in gunpowder (black powder) and an important agricultural fertilizer. One example is potassium superoxide, KO2, an orange solid that acts as a portable source of oxygen and a carbon dioxide absorber. Potassium is abundant in many whole foods, especially fruits, vegetables and fish. Atomic weight (average mass of the atom): 39.0983 4. This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. [117], The stable isotopes of potassium can be laser cooled and used to probe fundamental and technological problems in quantum physics. Certain Facts About Potassium. Only a very few fertilizers contain potassium nitrate. Potassium cyanide (KCN) is used industrially to dissolve copper and precious metals, in particular silver and gold, by forming complexes. [104] Low blood potassium may occur due to vomiting, diarrhea, or certain medications. [16], Metallic potassium is used in several types of magnetometers.[120]. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. Atomic symbol (on the Periodic Table of Elements): K (from the Latin word for alkali, kalium.) Until the 18th century no distinction was made between potassium and sodium. Potassium metal can react violently with water producing potassium hydroxide (KOH) and hydrogen gas. This reaction is exothermic and releases sufficient heat to ignite the resulting hydrogen in the presence of oxygen. The name is short for potassium aluminum sulfate. The two bosonic isotopes possess convenient Feshbach resonances to enable studies requiring tunable interactions, while 40K is one of only two stable fermions amongst the alkali metals. This was because early chemists did not recognise that "mineral alkali" (Na 2 CO 3, sodium carbonate, coming from deposits in the earth) and "vegetable ⦠This was because early chemists did not recognise that "mineral alkali" (Na2CO3, sodium carbonate, coming from deposits in the earth) and "vegetable alkali" (K2CO3, potassium carbonate, derived from wood ashes) are distinct from each other. Lincoln, S. F.; Richens, D. T. and Sykes, A. G. "Metal Aqua Ions" in J. McNaught, A. D. and Wilkinson,A. Davy isolated sodium by a similar procedure later in 1807. Origin of name : from the English word " potash " (pot ashes) and the Arabic word " qali " meaning alkali (the origin of the symbol K comes from the Latin word " kalium "). As a result, most commercial potassium compounds (often loosely called potash) are obtained via electrolysis from soluble potassium compounds, such as carnallite (KMgCl 3 â6H 2 O), sylvite (potassium chloride, KCl), polyhalite (K 2 Ca 2 Mg[SO 4] 4 â2H 2 O), and langbeinite (K 2 Mg 2 [SO 4] 3), which are found in ancient lake beds and seabeds. Potassium carbonate (K2CO3 or potash) is used in the manufacture of glass, soap, color TV tubes, fluorescent lamps, textile dyes and pigments. [125], This article is about the chemical element.
