Zinc Sulphate



Zinc sulfate describes a family of inorganic compounds with the formula ZnSO4(H2O)x. All are colorless solids. The most common form includes water of crystallization as the heptahydrate,[4] with the formula ZnSO4ยท7H2O. As early as the 16th century it was prepared on the large scale, and was historically known as "white vitriol". Zinc sulfate and its hydrates are colourless solids.

The main application of the heptahydrate is as a coagulant in the production of rayon. It is also a precursor to the pigment lithopone. It is also used as an electrolyte for zinc electroplating, as a mordant in dyeing, and as a preservative for skins and leather.
