An unstable condition where more solutes are dissolved in a solvent that can normally be held in solution; may be related to changes in temperature and/or pressure of solution

Supersaturation is the dissolving of a larger quantity of solute in a solution than would normally be possible. For example sea water is supersaturated with respect to carbonate by a factor of 3 or 4.

See dissolved gas concentrations.

in a saturated solution, the dissolved substance (solute) is in equilibrium with undissolved substance ie the rate at which solute particles leave the solution to return to their solid state is equivalent to the rate at which they dissolve into solution. A solution containing more than the equilibrium amount of the dissolved substance at a given temperature is supersaturated. A supersaturated solution is not stable and if a small seed crystal of the substance is added, the excess solute will crystallise out.

Is the state of a liquid containing more of a dissolved substance than is normal. In this case, the supersaturation refers to excessive amounts of oxalate and calcium in the urine.

an unstable situation where the pressure of a gas dissolved in the blood or tissues is higher than the ambient pressure of that gas.

Supersaturation occurs when the level of a substance in urine exceeds the level of that substance due to food intake. Many nutritional components not needed by the human body are excreted by the kidneys in the urine.

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.
