Zinc sulfate is an inorganic compound with the formula ZnSO₄. It forms hydrates ZnSO₄·nH₂O, where n can range from 0 to 7. All are colorless solids. The most common form includes water of crystallization as the heptahydrate, with the formula Zn SO₄·7H₂O. As early as the 16th century it was prepared on a large scale, and was historically known as "white vitriol" (the name was used, for example, in 1620s by the collective writing under the pseudonym of Basil Valentine). Zinc sulfate and its hydrates are colourless solids.
