The blue coloured copper sulphate crystals turns white due to the loss of water molecules. The formula of copper sulphate is CuSO4.5H2O. When copper sulphate is heated, it looses water molecules and hence it looses blue colour.

It can be converted into anhydrous copper sulphate when heated strongly. When water is added to white colour anhydrous copper sulphate ,it's colour changes to blue, indicating that the blue coloured copper sulphate pentahydrate is regenerated. So, it is a reversible chemical change.
