Hydrogen chloride. Hydrogen chloride, (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A solution of the gas in water is called hydrochloric acid. 1  Hydrogen chloride may be formed by the direct combination of chlorine (Cl2) gas and hydrogen (H2) gas; the reaction is rapid at temperatures above 250Â° C (482Â° F). 2  Hydrochloric acid is prepared by dissolving gaseous hydrogen chloride in water.
