Features / Description of Copper Sulphate CASNo. 7758-98-7
Copper (II) 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".
Copper (II) sulfate pentahydrate decomposes before melting at 150°C, losing two water molecules at 63°C, followed by two more at 109 °C and the final water molecule at 200°C.
