The alchemists of medieval times first made hydrogen chloride by heating sodium chloride with iron sulfate. The German chemist Johann Glauber made hydrogen chloride by the reaction of sodium chloride with sulfuric acid. This became the common method of preparing hydrogen chloride in the laboratories. During the 19^th century, scientists found that hydrogen chloride was a waste product of different industrial processes. Since hydrogen chloride was first made by salt, it was known as the spirits of the salt. Hydrochloric acid first came to use by scientists in the 18^th century. Scientists called hydrochloric acid muriatic acid, which comes from the Latin word meaning “pickled.”  One example from which hydrogen chloride was a waste product was from the production of soda ash. Many of hydrogen chloride and hydrochloric acid’s uses were not realized. Until many of the uses were found, hydrogen chloride and hydrochloric acid were dissolved in liquids and would be dumped into the sea.
