Question

What would you see, when a crystal of CuSO₄.5H₂O is placed in concentrated sulphuric acid? Give reason to explain your observation.

Solution

When a crystal of CuSO₄.5H₂O is placed in concentrated sulphuric acid, the water of crystallisation is lost due to dehydration and anhydrous copper sulphate is obtained. As a result, the blue colour of the crystal changes to white.

The balanced chemical reaction is given below:

CuSO₄.5H₂O + H₂SO₄ → CuSO₄ + H₂SO₄.5H₂O
