- A solution which contains the maximum amount of a given substance that it can dissolve in equilibrium. This maximum amount of solute will vary depending on the temperature and pressure.
- A solution containing the maximum amount of solid (solute) that can be dissolved in and remain in solution in a liquid solvent at a particular temperature. The amount of solute dissolved depends upon and usually increases with temperature. A supersaturated solution may be obtained by cooling a saturated solution but this is unstable and any shock will cause solid to crystallize out.
