WebSolutions may be prepared in which a solute concentration exceeds its solubility. Such solutions are said to be supersaturated, and they are interesting examples of nonequilibrium states (a detailed treatment of this important concept is provided in the text chapters on equilibrium). For example, the carbonated beverage in an open container … WebIn solution, liberated (soluble) molecules ( solute) are free to move about in random flow. This random flow permits for the possibility of two or more molecular compounds to interact. This interaction can potentiate intermolecular forces between the separate molecules and form a basis for a crystal lattice.

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. In a few cases the opposite effect occurs. The example of sodium sulfate in water is well-known and this was why it was used in early studies of solubility. WebThe AM supersaturated solutions were prepared by adding a stock solution of AM (1500 μg/mL in ACN) to the additive solutions, leading to a final ACN concentration of 2% (v / v) at 25 °C.

"WebSupersaturated Solutions. Whenever a solution contains more solute than it can hold, it is said to be supersaturated. It can be prepared by heating a saturated solution, adding more solute, and then cooling it gently. Excess dissolved solute crystallizes by seeding supersaturated solution with a few crystals of the solute. " - How is a supersaturated solution prepared
