What happens when copper sulphate crystals are heated strongly? Explain with the help of an example. (b) What happens when a few drops of water are added to anhydrous copper sulphate? Explain with the help of an equation.

(a) Copper sulphate crystals when heated strong it loses the water and the blue colour will turn to white CuSO4.5H2O → CuSO4 + 5H2O

(b) When water is added to anhydrous copper sulphate, it gets hydrated and turns blue. CuSO4 + 5H2O → CuSO4.5H2O
