Zinc chloride is the name of chemical compounds with the formula ZnCl2 and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water, also in ethanol and acetone. With excess water, acidic (pH ~ 4) zinc oxychloride is formed.
Zinc chloride has a rather low melting point and sublimed easily. This indicates that it has strong molecular character rather than ionic. Electron diffraction studies show that zinc chloride has linear Cl-Zn-Cl structure in the gas phase. Concentrated, aqueous solution dissolves starch and cellulose and silk. Hence the solution attacks paper and cannot be filtered through a filter paper.
