Question

define crystallization? how we can how we can you obtain pure crystals of copper sulphate from its impure sample

Answer 1

Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallization occurs in a crystallizer. 

Evaporate water from the copper sulphate solution so as to get a saturated solution. Cover the solution with a filter paper and leave it undisturbed at room temperature to cool slowly for a day. You will obtain the crystals of copper sulphate in the china dish. The crystallisation method is used to purify solids.

Answer 2

Crystallization is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.
Filter the impurities out.Evaporate water from the copper sulphate solution so as to get a saturated solution. Cover the solution with a filter paper and leave it undisturbed at room temperature to cool slowly for a day. You will obtain the crystals of copper sulphate in the china dish.


hope it helps!!!
