Brief Overview
Zinc Sulphate Heptahydrate occurs in nature as the mineral goslarite. It is soluble in water, and is generally immediately available in most volumes. Zinc Sulphate Heptahydrate belongs to the class of inorganic compounds, transition metal sulfates. These are inorganic compounds wherein the largest oxoanion is sulfate, and the heaviest atom not in an oxoanion is a transition metal. Zinc sulfate heptahydrate is an extremely strong acidic compound based on its acid dissociation constant used to describe the acidity of a particular molecule (pKa). Zinc sulfate heptahydrate is a potentially toxic compound.
Manufacturing Process
Zinc Sulphate Heptahydrate is produced by reacting zinc carbonate with dilute sulfuric acid.
ZnCO3 + H2SO4 + 6 H2O → ZnSO4·7 H2O + CO2
