Unsaturated Solution
Unsaturated solution explained in an easy to understand way:


Imagine trying to pack a suitcase for a trip, but you find that there's still room for more clothes. Just like how a suitcase with extra space can accommodate additional items, an unsaturated solution can dissolve more solute at a given temperature. In this analogy, the suitcase is the solution, the clothes are the solute, and the available space represents the capacity of the solution to dissolve more solute.

Unsaturated Solution: A solution that can dissolve more solute at a given temperature unsaturated solution. An unsaturated solution is one that has not reached its limit of dissolved solute and can still dissolve more.
