why is crystallization is better than evaporation

Answer 1

evaporation can leave some impurities in solid form with solute so pure solute may not be obtained. but crystallisation leaves only pure solute. so it is better than evaporation.

Answer:

____________________________________________________

Crystallization is the process of the formation of crystals of solid from a solution by cooling. It is used to separate and purify a solid that is present in the form of a liquid solution.

♦ Purification by crystallization is better than evaporation because of the following reasons:

✔Some solids like sugar may get decomposed on heating the solution to dryness.

✔The process of evaporation does not give crystals of the solid. Only a solid residue is left.

✔Soluble impurities do not get removed during evaporation of the liquid.
