Hydrogen Chloride

Hydrogen chloride is a chemical compound composed of the elements hydrogen and chlorine. It readily dissolves in water to produce a solution called hydrochloric acid. Both substances have many important industrial applications, including those in metallurgy, and the manufacture of pharmaceuticals, dyes, and synthetic rubber. Hydrochloric acid is found in most laboratories since its strong acidic nature makes it an extremely useful substance in analyses and as a general acid. Because hydrogen chloride and hydrochloric acid are so closely related, they are usually discussed together.
