Copper  sulfate, also known as cupric sulfate or copper sulphate, is the chemical compound with the

chemical formula CuSO4. This salt exists as a series of compounds that differ in their degree of hydration.

The anhydrous form is a pale green or gray-white powder, whereas the pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright

blue. Copper sulfate exothermically dissolves in water to give the aquo complex [Cu(H2O)6]2+, which has octahedral

molecular geometry and is paramagnetic. Other names for copper

(II) sulfate are "blue vitriol" and "bluestone".
