8. Concentration Calculation Practice
Complete the practice problems at your desk for 15 minutes. We will review the answers as a class

9. Think about: How does temperature affect solubility
Solubility Curves
Think about: How does temperature affect solubility

10. Solubility of solids
What effect does increasing the temperature have on the solubility of a solid?
In general it increases
Why?
Molecules move around more rapidly to dissolve quicker

11. Solubility of gases Gas solubility decreases with temperature increase
Why does this happen?
Molecules move faster, the gas particles escape the solution

12. To predict the quantity of solute that can dissolve at a given temperature, we use a Solubility Curve – Notes are in additional PPT

13. Solubility Curve Analysis
Complete the questions relating to the solubility curve. Ask Ms. Ose for help if you have questions

14. Exit Ticket
Would an 60 gram solution of KCl be unsaturated, saturated or supersaturated at a temperature of 80 oC
