Wikipedia Meaning and Definition on 'Supersaturation'
The term supersaturation refers to a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances. It can also refer to a vapor of a compound that has a higher (partial) pressure than the vapor pressure of that compound.
Small particles (seeds) can trigger the separation of the dissolved material from the solvent or condensation of the vapor. Seeds triggering the conversation of vapor are referred to as condensation nuclei, as in the case of water vapor. In the solid form these seeds can lead to the formation of crystallites or even large single crystals. Supersaturation is a measure of the deviation of a dissolved salt crystal from its equilibrium state.
Supersaturated solutions are prepared or result when some condition of a saturated solution is changed, for example temperature, volume (as by evaporation), or pressure.[See more about Supersaturation at Dictionary 3.0 Encyclopedia]
