What is characteristic of a supersaturated solution?

A supersaturated solution is characterized by the ability to dissolve more solute than what is normally possible at a given temperature and pressure. Because it holds more solute than the saturation point, any additional solute that is introduced can result in the formation of larger crystals. This occurs as the system adjusts to attain a new equilibrium; therefore, the excess solute does not remain dissolved and instead precipitates out, often forming larger crystals.

In contrast, a supersaturated solution may appear clear without any visible solids, but it is in a delicate state where any disturbance can lead to the crystallization of the excess solute. While it can temporarily hold additional solute, it does not mean that it cannot dissolve more solute at all; it simply means that the current amount of solute exceeds the saturation point. Hence, when more solute is added, it facilitates the growth of crystals from the dissolved solute rather than dissolving completely. This unique characteristic distinguishes supersaturated solutions in contrast to saturated solutions, where no additional solute can dissolve at equilibrium.
