Question

What happens when copper sulphate crystals are heated strongly? Explain with the help of an equation.

Answer 1

When copper sulphate (CuSO₄.5H₂O) crystals are heated strongly, they lose all the water of crystallisation and form anhydrous copper sulphate, which is white.
                     
               CuSO₄.5H₂O → CuSO₄ + 5H₂O
