A solution of a chemical compound in a liquid will become supersaturated when the temperature of the saturated solution is changed. In most cases solubility decreases with decreasing temperature; in such cases the excess of solute will rapidly separate from the solution as crystals or an amorphous powder.
For some solute-solvent combinations, a supersaturated solution can be prepared by raising the solubility (for example by increasing the temperature) to dissolve more solute and then lowering it (for example by cooling). Usually, the greater the temperature of the solvent, the more of a given solid solute it can dissolve.
Solubility is temperature dependent. A solution containing a higher concentration of solute than the solubility is said to be supersaturated. A supersaturated solution may be induced to come to equilibrium by the addition of a "seed" which may be a tiny crystal of the solute, or a tiny solid particle, which initiates precipitation.

The result is a supersaturated solution, which is metastable and will rapidly exclude the excess solute if a suitable nucleation site appears. [ 4 ] The concept of solubility does not apply when there is an irreversible chemical reaction between the two substances, such as the reaction of calcium hydroxide with hydrochloric acid ; even though ...
A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [ 12 ] [ 13 ] dissolving in their water of crystallization [ citation needed ] .
Trump's plan to 'drill. baby, drill' isn't likely to spark more oil production, lower gasoline prices, and help reverse inflation, analysts say.
The resultant solution is described as supersaturated, meaning that there is more solute dissolved in the solution than would be predicted by its solubility at that temperature. Crystallization can then be induced from this supersaturated solution and the resultant pure crystals removed by such methods as filtration and centrifugal separators ...
It’s a simple question with a complicated answer. Dogs eat grass all the time, but the reasons why are varied. Technically, eating non-food is known as Pica, a behavior condition associated with ...
