Saturated

Definition

A solution is saturated when it contains the maximum amount of solute that can dissolve at a given temperature and pressure. Any additional solute will remain undissolved.

5 Must Know Facts For Your Next Test

1. In a saturated solution, the rate of dissolution and crystallization of the solute are in dynamic equilibrium.
2. Temperature significantly affects the saturation point; higher temperatures usually increase the solubility of solids but decrease the solubility of gases.
3. The presence of other substances can influence a solution's saturation point through common ion effect or salting out.
4. Supersaturated solutions contain more solute than what is typically possible under normal conditions and are unstable.
5. Saturation can be tested using a seed crystal: if it dissolves, the solution is unsaturated; if it remains unchanged, it is saturated; if more crystals form, it is supersaturated.

Solubility:

The maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure.

Supersaturated Solution:

A solution that contains more dissolved solute than what can typically be dissolved at a certain temperature and pressure.

Dynamic Equilibrium:

A state where the rate of dissolution and crystallization of a solute in a solution are equal, resulting in no net change in concentration.
