(inorganic chemistry)
ZnCl2 Water- and alcohol-soluble, white, fire-hazardous crystals that melt at 290°C, and are irritating to the skin; used as a catalyst and in electroplating, wood preservation, textile processing, petroleum refining, medicine, and feed additives.

Zinc Chloride

 

ZnCl2, a white hygroscopic crystalline compound, with a density of 2.9 g/cm3, a melting point of 322°C, and a boiling point of 722°C. Its solubility in water is 79.8 percent (at 20°C). Concentrated solutions of zinc chloride are acidic. Zinc chloride is produced by dissolving zinc or zinc oxide in hydrochloric acid and then subjecting the solution to evaporation, by heating molten zinc in a stream of chlorine, or by other methods. It is used in calico printing and for the production of dental cements. It is also used as a wood preservative and to remove oxides from metal surfaces prior to welding.
