1. In Industry, it is a non-metallic liquid or solid substance that separates, or disassociates, into ions. It is used to transmit electric current through positively and negatively charged ions. This contrast to electrons in metals. The disassociation comes when the electrolyte melts or dissolves in water or a solvent. Salts, such as aluminum sulfate, ammonium chloride, copper sulfate, sodium chloride (table salt), and acids, such as hydrochloric and sulfuric, are all very common electrolytes. See also electrolysis. 2. In Medicine, it is bicarbonate, chloride, sodium, potassium and other ions present in blood plasma, cell fluid, and interstitial fluid. Interstitial fluid fills the spaces between the cells of a body and makes up a large part of its liquid area. It is important for normal metabolism and other essential body functions, such as exchange of nutrients and other substances among a body’s different organs and systems. Proper quantities and balanced concentration of these ions are essential in a living entity.
