Question

b) How would you show that copper sulphate crystals contain water of crystallisation?​

Answer 1

Answer:

Explanation:

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

Answer:

When copper sulphate crystals (chemical formula CuSO4. 5H2O) are heated strongly, they lose all the water of crystallisation and form anhydrous copper sulphate (CuSO4), which is white. This proves that blue copper sulphate crystals contain water of crystallisation.
