Answer 1

Answer:

Copper sulphate is basically a hydrated salt which contains five molecules of water of crystallisation and so is denoted by the chemical formula CuSO4.5H2O. It is blue in colour. On heating it loses water of crystallisation and changes into anhydrous copper sulphate (CuSO4), which is grey white in colour. When anhydrous CuSO4 is left open in air for sometime, it regains moisture from air converting back to the hydrated form, thereby restoring its blue colour.
