Is supersaturation possible if recrystallization occurs as a solution of a solid in water cools?

Supersaturation is possible

Explanation:

As a solution of solid in water cools, the dissolved solid would begin to reappear as the solution is now supersaturated at that lower temperature.

When the temperature of a solution is increased, more solute are able to dissolve in solution. A supersaturated solution is one that contains more than the required amount of solute needed to saturate the solution at that particular temperature.
