Odor: characteristic Use: Potassium Hydroxide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Hydroxide, the OH- anion composed of an oxygen atom bonded to a hydrogen atom, is commonly present in nature and is one of the most widely studied molecules in physical chemistry. Hydroxide compounds have diverse properties and uses, from base catalysis to detection of carbon dioxide. In a watershed 2013 experiment, scientists at JILA (the Joint Institute for Laboratory Astrophysics) achieved evaporative cooling of compounds for the first time using hydroxide molecules, a discovery that may lead to new methods of controlling chemical reactions and could impact a range of disciplines, including atmospheric science and energy production technologies. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards. |

| Potassium Hydroxide
Flavor: characteristic Potassium Hydroxide, KOH, is an inorganic compound, and commonly known as caustic potash. It can be used in the production of potassium chemicals, such as potassium carbonate (K2CO3) and potassium phosphates. Other uses also include manufacturing soaps, detergents, grease, catalysts, dyes, alkaline-electrolytic batteries and more. In the agriculture industry, potassium hydroxide is also used as a source in production of fertilizer for crops that are sensitive toward chloride ions. |
