Zinc sulfate is the inorganic compound with the formula ZnSO4 as well as any of three hydrates. It was historically known as “white vitriol”. It is a colorless solid that is a common source of soluble zinc ions.
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. Zinc sulfate is used to supply zinc sulfate, like many zinc compounds, can be used to control moss growth on roofs. It is used as in electrolytes for zinc plating, as a mordant in dyeing, as a preservative for skins and leather and in medicine as an astringent and emetic.
