Solution

Unsaturated solutions are solutions in which the amount of dissolved solute is less than the saturation point of the solvent and if the amount of dissolved solute is equal to the saturation point of the solvent, the solution is called a saturated solution.

If we add a small crystal of the same solute and try to stir by keeping the temperature constant if more solute does not dissolve then the solution is saturated and if the solution gets dissolved then it is the unsaturated solution.
