1. WARM UP Explain what an electrolyte is.
Describe how to identify and electrolyte.

2. Properties of Solutions
Chem II

3. IMF and Solubility
Things with similar and proportional IMF’s will dissolve in each other

4. IMF and Solubility Some ionic compounds are insoluble in water
Use Table 4.2

5. Temperature and Solubility
Solids
Increase with increasing temp

6. Temperature and Solubility
Gases
Decrease with increasing temp

7. Pressure and Solubility
Gases
Henry’s Law (William Henry)
More soluble with increasing pressure

8. Colligative Properties
Changes based on # of dissolved solute particles
Electrolytes dissociate
Twice as much impact

9. Colligative Properties
Vapor pressure lowering
Raoult’s Law (Francois Raoult)
Boiling point elevation
Based on vapor pressure

10. Colligative Properties
Freezing point depression
More disorder, harder to create crystals

11. Colligative Properties
Osmotic pressure
Pressure required to stop osmosis
Increases with concentration
Solute can’t “push back”

12. WRAP UP
Use the Solubility Table to determine the solubility of the following:
Ca(NO3)2 AgCl MgSO4
Li3PO4 BaSO4

13. WARM UP
1. List the 4 colligative properties of solutions, and describe how they are affected by increasing the concentration of the solution.

14. WRAP UP
Describe how the solubility of both solids and gases changes with increasing temperature and pressure.
