Zinc Sulphate USP
Zinc Sulphate also known as white vitriol is an inorganic compound that occurs in anhydrous, monohydrate, hexahydrate and heptahydrate forms. It has the formula ZnSO4 as well as any of three hydrates. It was historically known as “white vitriol”. All of the various forms are colorless solids. The heptahydrate form is commonly encountered.
The hydrates, especially the heptahydrate, are the primary forms used commercially. The main application is as a coagulant in the production of rayon. It is also a precursor to the pigment lithopone. It is also used to supply zinc in animal feeds, fertilizers and agricultural sprays, to control moss growth on roofs, as an electrolyte for zinc plating, as a mordant in dyeing, as a preservative for skins and leather and in medicine as an astringent and emetic.
