zinc sulfate
zinc sulfate chemical compound ZnSO 4 , a very water soluble, transparent, colorless, crystalline compound. It is commonly used as the heptahydrate, ZnSO 4 ·7H 2 O, and is commonly called white vitriol; it occurs naturally as the mineral goslarite, and can be prepared by reacting zinc with sulfuric acid. It is used to supply zinc in animal feeds, fertilizers, and agricultural sprays; in making lithopone; in coagulation baths for rayon; in electrolyte for zinc plating; as a mordant in dyeing; as a preservative for skins and leather; and in medicine as an astringent and emitic.
