1. Solutions

2. A solution has 2 parts
Solvent – the substance that does the dissolving (water)
Solute – the substance that is dissolved (kool aid)

3. Conductors? Some solutions will conduct electricity
These substances are called electrolytes
Ionic compounds are electrolytes

4. Nonelectrolytes
Solutes that make solutions that do not conduct electricity are called nonelectrolytes
Most organic compounds like sugar are nonelectrolytes

5. Rate of Solution This is the rate of how fast the solute is dissolved
The process of dissolving only happens at the surface of the solute
Small pieces will dissolve faster than one large piece
Solute will dissolve faster in hot solvent

6. Solubility
Solubility is a measure of how much of a solute that can be dissolved in a give solvent
Sugar and salt have a high solubility in water
Salt has a low solubility in alcohol

7. Factors of Solubility Temperature
Higher temperatures will increase the amount of solid solute that can dissolve
Higher temperatures will decrease the amount of gas that can be dissolved

8. Pressure
Higher pressure increases the amount of gas that will dissolve in a liquid
Pressure has no effect on dissolving a solid or liquid in a liquid

9. Concentrations Solutions with a high amount of solute are concentrated
Solutions with a low amount of solute are dilute
Solutions that contain as much solute as possible are saturated
Supersaturated solutions contain more than saturated amount
