22% Zinc Sulphate Heptahydrate
Zinc sulfate (ZnSO4) is a colorless crystalline, watersoluble chemical compound. The hydrated form, ZnSO4 7H2O, the mineral goslarite, was historically known as "white vitriol" and can be prepared by reacting zinc with aqueous sulfuric acid. It may also be prepared by adding solid zinc to a copper(II) sulfate solution.
