Wikipedia
Zinc chloride is the name of chemical compounds with the formula ZnCl and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. ZnCl itself is hygroscopic and even deliquescent. Samples should therefore be protected from sources of moisture, including the water vapor present in ambient air. Zinc chloride finds wide application in textile processing, metallurgical fluxes, and chemical synthesis. No mineral with this chemical composition is known aside from the very rare mineral simonkolleite, Zn(OH)Cl·HO.
Usage examples of "zinc chloride".
Hexachlorethane in the Shaggie reacts vigorously with metallic zinc in the zincal floor and forms zinc chloride.
Reaction liberates such great heat that the zinc chloride is immediately evaporated, and a dense cloud o' white smoke is generated!
