Which method is better for recovering sugar from sugar solution: evaporation or crystallization? Give reason for your answer.

Answer :

The process of evaporation gives residue which may contain impurities. When there is requirement to obtain solid without impurity, crystallization method is preferred.

In general practice, impure solids are obtained by evaporation and are further purified by crystallization. Sugar crystal cannot be obtained by simple evaporation technique because sugar gets charred on heating to dryness. In such cases, crystallization technique is applied.
