Hydrochloric acid is a corrosive, strong mineral acid with many industrial uses. A colorless, highly pungent solution of hydrogen chloride (HCl) in water, when it reacts with an organic base it forms a hydrochloride salt.
Hydrochloric acid was historically called acidum salis, muriatic acid, and spirits of salt because it was produced from rock salt and green vitriol (by Basilius Valentinus in the 15th century) and later from the chemically similar common saltand sulfuric acid (by Johann Rudolph Glauber in the 17th century). Free hydrochloric acid was first formally described in the 16th century by Libavius. Later, it was used by chemists such as Glauber, Priestley, and Davy in their scientific research.
With major production starting in the Industrial Revolution, hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride for PVC plastic, and MDI/TDI for polyurethane. It has numerous smaller-scale applications, including household cleaning, production of gelatin and other food additives, descaling, and leather processing. About 20 million tonnes of
hydrochloric acid are produced worldwide annually.[citation needed] It is also found naturally in gastric acid.
Hydrochloric acid was known to European alchemists as spirits of salt or acidum salis (salt acid). Both names are still used, especially in other languages, such as German: Salzsäure, Dutch: Zoutzuur, Swedish: Saltsyra, Turkish: Tuz Ruhu, Polish: kwas solny, Bulgarian: солна киселина and Chinese: 鹽酸. Gaseous HCl was called marine acid air.
The old (pre-systematic) name muriatic acid has the same origin (muriatic means “pertaining to brine or salt”, hence muriate means hydrochloride), and this name is still sometimes used.[1][4] The name hydrochloric acid was coined by the French chemist Joseph Louis Gay-Lussac in 1814.
