The first edition of the Merck's Index was published in 1889 by the German chemical company Emanuel Merck and was primarily used as a sales catalog for Merck's growing list of chemicals it sold. [2] The American subsidiary was established two years later and continued to publish it.
Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.

In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French. An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid.
It can also be produced by the addition of hydrochloric acid to a hot, concentrated solution of mercury(I) compounds such as the nitrate: [2] Hg 2 (NO 3) 2 + 4 HCl → 2 HgCl 2 + 2 H 2 O + 2 NO 2. Heating a mixture of solid mercury(II) sulfate and sodium chloride also affords volatile HgCl 2, which can be separated by sublimation. [2]
AuCl 3 is a Lewis acid and readily forms complexes. For example, it reacts with hydrochloric acid to form chloroauric acid (H[AuCl 4]): [15] HCl + AuCl 3 → H + + [AuCl 4] −. Chloroauric acid is the product formed when gold dissolves in aqua regia. [15] On contact with water, AuCl 3 forms acidic hydrates and the conjugate base [AuCl 3 (OH)] −.
