Zinc-chloride is one of the important products in the inorganic salt industry. Zinc-chloride soluble in water, is the largest solid salt solubility (25 ° C, 432 g / 100 g), its reason is soluble in water to form complex acid H [ZnCl2 (OH)]. Soluble in m ethanol, ethanol, glycerin, a cetone, ether, insoluble in liquid a mmonia. Strong deliquescence, can absorb moisture from the air and deliquescence. It has the properties of dissolving metal oxides and cellulose. Molten zinc-chloride has excellent electrical conductivity. Intense white smoke forms in the heat. Zinc-chloride is corrosive and toxic.

Corrosion inhibitor for water treatment.
Zinc chloride is easily soluble in water, and it is hydrolyzed in water to produce insoluble colloidal particles, which makes the composite corrosion inhibitor cloudy and not clear and transparent. Over time, these insoluble colloidal particles gradually aggregate and precipitate
Industrial use
It can be used as electrolyte substance of batteries; Dehydration or condensing agent in organic compound industry; Activator of cation exchange resin; Impregnant in producing polypropylene cyanogens; Intermedium dyeing agent, silk agent, and sizing agent in dyeingweaving industries. It can be used to produce active dyestuff and cation dyestuff.
