Salt can be recovered from its solution by evaporation. Suggest some other technique for the same?

Answers (1)

Solution:
By the process of evaporation, we can find dry salt as the water gets evaporated but salt remain there. This process is a slow process.
We can think of another method:
The name of this process is distillation. It is similar to evaporation but we will not lose water in this case.
The boiling point of salt is very large in comparison of water.
On heating, the water will start boiling and we can collect the steam and condense it back in water.
Finally in the pot, we will left with only salt.
Note: The solubility of salt in water is independent of temperature, hence we can use crystallization method.
