Question

Crystalization is better technique than simple evaporation technique.Justify this statement by giving two reasons

Answer 1

Answer:

Explanation:

Crystallisation and evaporation are both separation techniques.

However crystallisation is considered better because crystallisation helps in separating impurities from a mixture.

For example-- when salt is obtained from sea water using evaporation, it will let water evaporate and salt will be left behind. But still there will be many impurities present in salt as there are many other kinds of salts present in sea water.

In case of crystallisation you will get the pure form of salt.

That's why crystallisation is considered bette

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.
