Heat of hydration of copper sulphate. Water being poured from a test tube onto anhydrous copper (II) sulphate (white). The copper (II) sulphate forms hydration bonds with the water in an exothermic (heat-producing) reaction, resulting in hydrated copper (II) sulphate (blue). The heat of the reaction is enough to produce steam and disturb the powder.
