Answer Details

The solution is saturated. A saturated solution is a solution that contains the maximum amount of solute that can be dissolved in the solvent at a given temperature and pressure. When a crystal is added to a saturated solution, it will not dissolve because there is no more room for additional solute to dissolve. The solution remains unchanged because the concentration of solute in the solution is already at its maximum limit, and no more solute can be dissolved.
