20g of sodium chloride is dissolved in 100 mL of water. How will you test whether the given solution is saturated or unsaturated at the given temperature?

A solution is said to be saturated if it has with the maximum possible amount of solute that it can dissolve whereas a solution is said to be unsaturated if a solution contains less than the maximum amount of solute. Thus, to test if a solution is saturated or not we need to add sodium chloride, if it dissolves then it is not saturated and if it does not dissolve then its unsaturated.
