three advantages are
1) in evaporation the soluble impurities (and insoluble impurities sometimes) are mixed but crystallization process separates the soluble and insoluble impurities from the solid
2) in evaporation the resultant object obtained is in powdery form but in crystallization it is pure crystal
3) In evaporation, the solution is heated to dryness , so some solids like sugar may get charred but it is not so in process of crystallization
hope this helps

Answer:
Advantages of crystallization over evaporation -
- Crystallization doesn't cause charring of substance (which is a problem with evaporation).
- Impurities get removed attaining high purity.
- Low temperature & lesser energy requirement in crystallization (lot of energy spent in evaporation).
