Question

What are the matetials required to show that hydrated copper sulphate crystals contain water of crystallisation​

Answer 1

When copper sulphate (blue vitriol ,CuSO4.5H2O) is heated then its blue colour fades away and it turns from Blue to White and becomes anhydrous copper sulphate (CuSO4) this happens because copper sulphate loses its water of crystallization. In this way we can show that copper sulphate contains water of crystallization.

Answer 2

When copper sulphate is heated then it's blue colour fades away it turns from Blue to white and become an hydrous copper sulphate thus happens because copper sulphate loses its water of crystallisation.
