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.
The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide.At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor.
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.
Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds that contain one or more carbon–chlorine bonds. [1] The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) includes common examples. The wide structural variety and divergent chemical ...
Hydrolysis gives arsenous acid and hydrochloric acid: AsCl 3 + 3 H 2 O → As(OH) 3 + 3 HCl. Although AsCl 3 is less moisture sensitive than PCl 3, it still fumes in moist air. [10] AsCl 3 undergoes redistribution upon treatment with As 2 O 3 to give the inorganic polymer AsOCl. With chloride sources, AsCl 3 also forms salts containing the ...
Chloric acid, H Cl O 3, is an oxoacid of chlorine, and the formal precursor of chlorate salts. It is a strong acid ( p K a ≈ −2.7) and an oxidizing agent . Properties
Trichlorosilane (TCS) is an inorganic compound with the formula HCl 3 Si. It is a colourless, volatile liquid. Purified trichlorosilane is the principal precursor to ultrapure silicon in the semiconductor industry. In water, it rapidly decomposes to produce a siloxane polymer while giving off hydrochloric acid.
Alternatively, it may be prepared by adding hydrochloric acid to bismuth oxide and evaporating the solution. Bi 2 O 3 + 6 HCl → 2 BiCl 3 + 3 H 2 O. Also, the compound can be prepared by dissolving bismuth in concentrated nitric acid and then adding solid sodium chloride into this solution. [2] Bi + 6 HNO 3 → Bi(NO 3) 3 + 3 H 2 O + 3 NO 2
