Definition
solution saturation concentration of a particular solute at thermodynamic equilibrium
Explanatory Notes
Equilibrium solubility is the saturation limit at thermodynamic equilibrium: the greatest amount of a solute that can remain dissolved under specified conditions while coexisting in equilibrium with a separate phase of that solute (e.g., a solid/crystalline phase, precipitate, separate liquid phase, or gas phase). The value depends on the stated conditions, including temperature, pressure, and solvent composition, and in many practical systems also depends on pH, ionic strength, and the presence of other solutes or additives. Equilibrium solubility can be reported in multiple composition forms (e.g., molarity, molality, mass concentration, mass fraction, mole fraction), provided the solute, solvent, and equilibrium conditions are specified.
Examples
- the equilibrium saturation concentration of sodium chloride in water at 20 °C; the equilibrium saturation concentration of glucose in aqueous solution at 25 °C; the equilibrium saturation concentration of dissolved oxygen in culture medium at 37 °C under a defined oxygen partial pressure; the equilibrium saturation concentration of carbon dioxide in buffer at pH 7.2 under 5% CO₂;
