hydrochloric acid

noun    (Concise Encyclopedia)

Solution in water of hydrogen chloride (HCl), a gaseous inorganic compound. It is a strong acid, virtually completely dissociated (see dissociation) into hydronium cations (HO+) and chloride anions (Cl), and is corrosive and irritating. The acid reacts with most metals, to produce hydrogen and the metal's chloride, and with oxides, hydroxides, and many salts. It is used extensively in industrial processing of metals and concentrating of some ores; in boiler scale removal, food processing, metal cleaning, and pickling; and as a chemical intermediate, laboratory reagent, and alcohol denaturant (see ethanol). Hydrochloric acid is present in the stomach's gastric juice and is involved in the devlopment of peptic ulcers.
