Copper Sulphate Pentahydrate

Copper (II) sulfate, also known as cupric sulfate or copper sulphate, is the inorganic 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 (II) 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 (302 °F), losing two water molecules at 63 °C (145 °F), followed by two more at 109 °C (228 °F) and the final water molecule at 200 °C (392 °F).  Dehydration proceeds by decomposition of the tetraaquacopper(2+) moiety, two opposing aqua groups are lost to give a diaquacopper(2+) moiety. The second dehydration step occurs with the final two aqua groups are lost. Complete dehydration occurs when the only unbound water molecule is lost. At 650 °C (1,202 °F), copper (II) sulfate decomposes into copper (II) oxide (CuO) and sulfur trioxide (SO3).
Copper sulfate reacts with concentrated hydrochloric acid to give tetrachlorocuprate(II):

Cu2+ + 4 Cl− → CuCl2− 4

It also reacts with more reducing metals to give copper metal and the corresponding oxidized metal, e.g.

CuSO4 + Zn → ZnSO4 +Cu
