➢ Filter the solution to remove impurities.
➢ Heat the copper sulphate solution on water bath.
➢ When small crystals form on glass rods, stop heating.
➢ Allow the saturated solution to cool slowly.
➢ Crystals of pure copper sulphate are formed.
➢ Separate the copper sulphate crystals by filtration and dry.
