When Blue Crystals Of Copper (Ii) Sulphate Are Added To Concentrated Sulphuric Acid Crystals Turn White

When blue crystals of copper (II) sulphate are added to concentrated sulphuric acid crystals turn white. Why ?


Hydrated copper (II) sulphate, when added to concentrated sulphuric acid, loses water of crystallization and thus white anhydrous copper (II) sulphate is formed. The blue coloured hydrated copper (II) sulphate turns white due to the loss of water of crystallization.
