Question
Which method is better for recovering sugar from sugar solution: evaporation or crystallization? Give reason for your answer.
✓
Answer
Crystallisation is better method for recovering sugar from sugar solution than evaporation because:
- Sugar decomposes or get charred on heating to dryness during evaporation. There is no such problem in crystallization.
- The soluble impurities do not get removed in the process of evaporation. But such impurities get removed in crystallization.
