hydrochloric acid (HCl)
Hydrochloric acid is used in petroleum production, as a chemical intermediate, in ore reduction, food processing, pickling, and metal cleaning. It was formerly known as "spirits of salt." Stomach acid Dilute hydrochloric acid is produced by the stomach lining and is important in the digestion of proteins. Excessive acid production, which may be stimulated by stress or tobacco smoking, results in the condition known and hyperchlorhydria and may cause gastric ulcers. In acid reflex (backflow of stomach acid into the esophagus), hydrochloric acid may cause esophagitis and heartburn.
