ZINC CHLORIDE (ZnCl2)
Zinc chloride is one of the important zinc componds. It is stable in the vapour phase upto 900oC. It is very hygroscopic, extremely water soluble, and soluble in organic liquids such as alcohols, esters, ketones,ethers, amides and mitrictes. Hydrates with 1, 1.5, 2.5, 3, and 4 molecules of water have been identified and great care must be expressed to avoid hydration of the anhydrous form. Aqueous solution of zinc chloride are acidic (pH=1.O for 6 m ),and when partially neutralized form slighly soluble basic chlorides eg. Zncl2 and 4 Zn(…
