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 Zn SO₄·7H₂O. As early as the 16th century it was prepared on the large scale, and was historically known as "white vitriol"^[5] (the name was used, for example, in 1620s by the collective writing under the pseudonym of Basil Valentine)^{[citation needed]}. Zinc sulfate and its hydrates are colourless solids.
