After the passage of the act, soda ash producers were obliged to absorb the waste gas in water, producing hydrochloric acid on an industrial scale. [25] [26] In the 20th century, the Leblanc process was effectively replaced by the Solvay process without a hydrochloric acid by-product. Since hydrochloric acid was already fully settled as an ...
Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO 3 + 3 HCl → NOCl + Cl 2 + 2 H 2 O. as evidenced by the fuming nature and characteristic yellow color of aqua regia.
Hydrogen chloride gas was converted to chlorine gas, which was then used to manufacture a commercially valuable bleaching powder, and at the same time the emission of waste hydrochloric acid was curtailed. To some extent this technically sophisticated process superseded the earlier manganese dioxide process. [1]
Anhydrous SnCl 2 is prepared by the action of dry hydrogen chloride gas on tin metal. The dihydrate is made by a similar reaction, using hydrochloric acid: Sn (s) + 2 HCl (aq) → SnCl 2 (aq) + H 2 (g) The water then carefully evaporated from the acidic solution to produce crystals of SnCl 2 ·2H 2 O.

Antimony trichloride solution in hydrochloric acid. SbCl 3 is readily hydrolysed and samples of SbCl 3 must be protected from moisture. With a limited amount of water it forms antimony oxychloride releasing hydrogen chloride: SbCl 3 + H 2 O → SbOCl + 2 HCl. With more water it forms Sb 4 O 5 Cl 2 which on heating to 460° under argon converts ...
The dihydrate, FeCl 2 (H 2 O) 2, crystallizes from concentrated hydrochloric acid. [7] The dihydrate is a coordination polymer. Each Fe center is coordinated to four doubly bridging chloride ligands. The octahedron is completed by a pair of mutually trans aquo ligands. [8] Subunit of FeCl 2 (H 2 O) 2 lattice.
It is prepared by the reaction of chlorine with acetic acid in the presence of a suitable catalyst such as red phosphorus. This reaction is Hell–Volhard–Zelinsky halogenation. CH 3 COOH + 3 Cl 2 → CCl 3 COOH + 3 HCl. Another route to trichloroacetic acid is the oxidation of trichloroacetaldehyde.
