A saturated solution is a solution in which the maximum amount of solute has been dissolved.[1] This amount is set by the chemical properties of the solvent and solute, as well as the temperature and pressure of the system.
In some cases it is possible to have an amount of solute dissolved in the solution which is greater than the normal maximum solubility of the system. In this case the system is supersaturated. Since solubility of liquids generally goes up with temperature, one way to supersaturate a solution is by heating the system, creating a saturated solution, then gently reducing the temperature. If no solute falls out of solution, then the solution is has more solute dissolved than it theoretically should be able to at the given temperature.
