The most common use of the term saturation in chemistry is:
This point of maximum concentration, the saturation point, depends on the temperature of the liquid as well as the chemical nature of the substances involved. If a change in conditions (e.g. cooling) means that the concentration is actually higher than the saturation point, the solution has become 'supersaturated'.
