When the maximum amount of solid is dissolved in a solvent, the solution is called a saturated solution.

Here's why:

* Saturated Solution: A solution that holds the maximum amount of solute that can dissolve at a given temperature and pressure. Any additional solute added will simply settle to the bottom.

* Unsaturated Solution: A solution that can still dissolve more solute at a given temperature and pressure.

* Supersaturated Solution: A solution that holds more solute than it normally should at a given temperature and pressure. These solutions are unstable and any disturbance can cause the excess solute to crystallize out.
