1. Q2:
Draw a picture of a solution and label the parts.
How can you tell a solution from a suspension or a colloid?
Sketch a distillation apparatus and describe how it works.

2. 6
days

3. Unit Exam
Friday

5. Today’s Objective:
Using a solubility graph, I can determine how much solute can be added to a solution.

6. 1st period

7. from a liquid solution because it won’t or can’t dissolve
Precipitant:
A solid that comes
from a liquid solution because
it won’t or can’t dissolve
* From a chemical change
* From a physical change

8. Solubility: The amount of a substance that can be dissolved

9. Factors That Affect Solubility
1. Nature of
the reactants
2. Polarity

10. 3. Temperature:
Heating up allows more solute to be dissolved.

11. 4. Surface area
Increase the surface area will increase the rate it dissolves.

12. 5. Stirring will increase the surface area exposed and increase solubility.

13. at a certain temperature

17. Describe a solution at 30C with 50 g
Saturated

18. Which substance is most soluble in H20?
Yellow, NaNO2 under 70C
Blue, KNO3 over 70C
Which substance is most soluble in H20?

19. Supersaturated
Describe the saturation of a solution containing 100 g of potassium bromide solution at 60 C

20. Sodium Nitrate
The most soluble at 0 C

21. Solubility increases most between 40 & 60 C
Sodium Acetate
Solubility increases most between 40 & 60 C

22. Changes the least as temperature changes
Table Salt
Changes the least as temperature changes

23. How would cooling a solution affect its solubility?
It would hold less solute.

24. It would increase. How would decreasing the size of a solute’s
particle affect
its solubility?
It would increase.

25. A super saturated solution is cooled to room temperature
A super saturated solution is cooled to room temperature. What would it create?
Crystals
