What is supersaturated solution what is done to make a solution supersaturated?

A supersaturated solution is a solution that contains more solute than it can normally dissolve at a given temperature and pressure. To create a supersaturated solution, a solvent is heated to dissolve a greater amount of solute than possible at cooler temperatures, and then the solution is carefully cooled. As the temperature decreases, the solute remains dissolved beyond its normal saturation point until disturbed, after which it may crystallize out.
