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?

AcademicChemistryNCERTClass 6

In order to get the salt back from the water, there are two methods to do so:
  1. Water can be removed from the salt solution by heating it on a stove.
  2. By keeping it in the sun on a plate for a few hours for evaporation.

Evaporation is defined as a slow conversion of water into its vapour state. Once the water gets evaporated, we get the salt back.
