In a saturated solution, what can no longer be dissolved?

In a saturated solution, the term refers to a state where the maximum amount of solute has been dissolved in a specific amount of solvent at a given temperature and pressure. At this point, the solution is in equilibrium with the undissolved solute, meaning that any additional solute introduced into the solution cannot dissolve and will remain as a solid precipitate. This situation occurs because the solution has reached its solubility limit for that particular solute under the given conditions.

The other components, such as the solvent and gas, can still interact with the solute or be present in the solution. The solvent is the medium in which the solute is dissolved, and although gas may be influenced by temperature and pressure changes, it does not become a focus when discussing solubility limits of solids in saturated solutions. Therefore, it is correct to identify that in a saturated solution, no additional solute can dissolve, highlighting the saturated state of the solution.
