In the concept of dissolving a soluble compound in water to form an aqueous solution, there are three types of solution: unsaturated, saturated and supersaturated/
Saturated solution is the limiting boundary among the three. This solution is made when the maximum amount of salt is added to the water. This can be manifested when you add another pinch of salt but does not dissolve even if you dissolve it. This is because it has reached its limit. Below this is the unsaturated solution where it dissolves all of the solute. Supersaturated solution is when you force the solution to dissolve the additional salt even if it saturated already. This can be possible if you heat the solution.
Therefore, since the solution still dissolves the salt without heating and even without stirring, the resulting solution is still an unsaturated solution.
