• Evaporation

  evaporation is used to separate and retain the solid solute from a solution if the solute does not decompose on heating or contain water of crystallisation.
• crystallisation

  is used to separate and retain the solid solute from a solution, especially if the solid contains water of crystallisation, e.g. copper sulphate crystals from copper sulphate solution
