Question

Why is crystallisation considered a better technique than evaporation?

Answer 1

Answer:

crystallization is the process of slow precipitation of solid crystals of a substance from a concentrated homogeneous solution examples of compound prepared by crystallization include Potash alum crystallization is better than evaporation as - 1) sometimes solid particles decompose or some get charged on heating like sugar second. 2) place updating using evaporation some impurities may be left in the solution on operation solid maybe form contaminate.

Answer 2

Why crystalization is better than evaporation?

1. It occurs on the entire surface.
2. we get solid in the pure crystallized form.
3. The soluble impurities get removed in this process.
4. It doesn't require very high temperature conditions.
