Which method is better for recovering sugar from sugar solution (evaporation/crystallization) Give reason for your answer.

Dear Student,

Crystallization is a solid liquid separation technique in which the solute is transferred from the liquid solution into the solid state. The solid is obtained in the pure crystallized form. As compared to evaporation, it is considered as a better method to obtain sugar from sugar solution because:

  1. the sugar will be obtained in pure crystalline form. In case of evaporation, impurities would be present.
  2. When we obtain sugar from water, it may be possible that along with water molecules, some sugar molecules may also be lost as some of the sugar may decompose due to heating.
