1. Saturated Vs. Unsaturated

2. Concentration
Concentration is the amount of solute dissolved in a given quantity of solvent.

3. Diluted Solutions
Diluted solutions are solutions with a low concentration of solute.
Weak Juice

4. Concentrated Solutions
Concentrated solutions are solutions that contain a high amount of solute.
Strong Coffee

5. Unsaturated
Unsaturated solutions are still able to dissolve more solute.
The solution still contains empty spaces between the solute and solvent particles.
Both dilute and concentrated solutions are unsaturated.

6. Saturated
Saturated solutions contain the maximum amount of solute that can dissolve.
All of the spaces between the solute and the solvent are filled.
Any more solute that is added will not dissolve.

7. Saturated Vs. Unsaturated
Unsaturated: Saturated:

8. Supersaturated
Supersaturated solutions contain more solute than can dissolve in a solution.
Solute will remain undissolved in a supersaturated solution.

9. How do we get a Supersaturated Solution?
A hot saturated solution at a high temperature is allowed to cool gradually.
As the solutions cools the particles loose energy, and attraction between the crystals brings the particles back together again.
As the solutions cools you will begin to see particles of solute in the solution, it will become supersaturated.

10. Solubility
The solubility of a solute is the exact amount of solute required to form a saturated solution at a given temperature.
The solubility for every solvent/solute combination varies drastically.
