Which test will you carry out to find out if a given solution is saturated or unsaturated or supersaturated?

Add a few drops of solute in the solution and try to stir by keeping the temperature constant.

1. If more solute does not dissolve in the given solution, then it will be a saturated solution.
2. If the solute gets dissolved, then it is an unsaturated solution.
3. If on slightly disturbing the solution by shaking, stirring, scratching the wall of container or adding a solute crystal to the solution, the additional amount of the solute precipitates out, then the solution is a supersaturated solution.
