Explain how, impure copper sulphate can be purified by crystallization.
Impure copper sulphate can be purified by crystallization.
Crystallization is a chemical solid-liquid separation technique in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.
The steps of purifying impure copper sulphate is given below:
- Impure copper sulphate can be dissolved in minimum amount of water to prepare copper sulphate solution. It is then filtered to remove insoluble impurities.
- The copper sulphate solution is heated gently on a water bath to evaporate water and obtain a saturated solution.
- Heating is stopped when all the water evaporates.
- The saturated solution of copper sulphate is then allowed to cool slowly.
- Crystals of pure copper sulphate are formed leaving behind impurities.
