Question

Dissolve two spoons of common salt in half a cup of water. Now if you want to get the salt back, what will you do?

Answer 1

We can follow different steps :

• To get salt back from a half cup of water we can either heat the water in a pan on a stove or we can keep the water out in sun in a plate.
• Heat will evaporate the water in form of water vapour leaving behind the salt.
• In both ways, the water will get evaporated in the form of water vapours and the salt will have remained back in the pan.
