Answer
| Supersaturated solution | Saturated solution |
|---|---|
| The solution which can hold or contains more of the solute at a given temperature than that present in a saturated solution is called supersaturated solution. | When the solvent cannot dissolve more of the solute at that temperature, the solution that is formed is called a saturated solution at that temperature. |
A saturated solution of potassium chloride is prepared in boiling water. If this solution is cooled excess potassium chloride separates out from the hot saturated solution. The hot solution therefore contains more of the solute dissolved in than it can hold at that given temperature and is thus called a supersaturated solution.
