1. Solutions

2. Suspension
A mixture in which particles can be seen and easily separated by settling or filtration.

3. Solutions
Water and table salt form a solution, a well-mixed mixture. If you taste a salt solution, any sip tastes just as salty as the next.

4. Solvents and Solutes
All solutions have at least two parts: the solvent and the solute.
The solvent is the part of a solution present in the largest amount. It dissolves the other substances.
The solute is the substance that dissolves in the solvent.
In many common solutions, the solvent is water.

5. Examples of Common Solutions
Solute
Solvent
Solution
Gas
Air (oxygen and other gases)
Liquid
Soda water (CO2 in water)
Antifreeze (ethylene glycol in water)
Solid
Dental filling (silver in mercury)
Ocean water (salt in water)
Brass (zinc and copper)

6. Solubility
A measure of how well a solute can dissolve in a solvent at a given temperature.
When you’ve added so much solute that no more dissolves, you have a saturated solution.
If you can continue to dissolve more solute, you still have an unsaturated solution.

7. Solubility Continued
The solubility of a substance tells you the limit on how much you can add before you make a saturated solution.
