Question

Write two advantages of crystallization technique over evaporation technique.?

Answer 1

Crystallisation is the process of slow precipitation of solid crystals of substance from a concentrated homogeneous solution. It is basically a separation method in which a substance is transferred from the liquid (i.e. solution) phase to the solid state. The substance is thus obtained in pure crystalline form and has no impurity. It is used by chemists for the purification of solid substances.

Answer 2

Write two advantages of crystallization technique over evaporation technique.?

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.
