HYDROCHLORIC ACID

Hydrochloric acid (also known as chlorhydric acid, muriatic acid and spirit of salt) is a compound of chlorine and hydrogen that occurs in the human stomach. It was discovered in 1648 by Johann Glauber and first prepared in 1772 by Joseph Priestley, while its constitution as a compound solely of chlorine and hydrogen was determined in 1810 by Humphry Davy. Today the term is restricted to the aqueous solution of hydrogen chloride (which is a gas normally).
