20.) ANSWER:
Saturated solution are those solution in which additional solute is not dissolved, i.e. maximum amount of solute dissolved in a solution then that solution is known as saturated solution.
Unsaturated solution are those solution in which more solute can be added and that solute dissolved in the solution.
Supersaturated solution are those solution in which more solute amount are added which is not dissolved by solvent. So we can see the solute particles by naked eyes.
Hence, in a given question added Nacl is dissolved in aquous solution of NaCl. So, this solution is unsaturated solution.
