Zinc Sulphate

Zinc sulfate is an inorganic compound. It is used as a dietary supplement to treat zinc deficiency and to prevent the condition in those at high risk.^[3] Side effects of excess supplementation may include abdominal pain, vomiting, headache, and tiredness.^[4]

The most common form includes water of crystallization as the heptahydrate,^[5] with the formula ZnSO₄•7H₂O. It was historically known as “white vitriol“. Zinc sulfate and its hydrates are colourless solids.

Uses[edit]

Minerals[edit]

As a mineral, ZnSO₄•7H₂O is known as goslarite. Zinc sulfate occurs as several other minor minerals, such as zincmelanterite, (Zn,Cu,Fe)SO₄•7H₂O (structurally different from goslarite). Lower hydrates of zinc sulfate are rarely found in nature: (Zn,Fe)SO₄•6H₂O (bianchite), (Zn,Mg)SO₄•4H₂O (boyleite), and (Zn,Mn)SO₄•H₂O (gunningite).
