Why do blue copper sulphate crystals become white on heating?

Answer and explanation

Correct answer: Water of crystallisation is removed

The governing concept is water of crystallisation: some salts contain a fixed number of water molecules within their crystal structure. Blue copper sulphate is CuSO₄·5H₂O. On heating, these water molecules are driven off, producing anhydrous CuSO₄, which is white. Thus option A is correct. The copper does not become a gas, sulphate does not turn into water, and oxygen is not added.
