Solution
When copper sulphate crystals are heated strongly, they lose all the water of crystallisation and form anhydrous copper sulphate (which is white).
\[\ce{\underset{(Blue)}{\underset{Hydrated copper sulphate}{CuSO4*5H2O}} ->[Heat] \underset{(White)}{\underset{Anhydrous copper sulphate}{CuSO4}} + \underset{(Goes away)}{\underset{Water}{5H2O}}}\]
