Answer 2

To separate common salt dissolved in water

Dissolve a teaspoon full of salt in about 50 ml water taken in a beaker. Heat this salt solution. You will notice that as the water evaporates, the amount of solution decreases. Let the water evaporate completely. Now, you will find white residue i.e. salt left behind the beaker.
