Today I will be able to:
Apply molarity, molality, mole fraction and dilution calculations to a quiz
Construct a solubility curve for a compound
Evaluation/Assessment:
Informal Assessment – monitoring student interactions and questions as they complete the quiz and worksheet
Formal Assessment – analyzing student responses to the quiz, worksheet and exit ticket
Common Core Connection
Make sense of problem and persevere in solving them
Look for and make use of structure
Use appropriate tools strategically

4. Warm - Up As you come in write your name on a sticky note
Place your electronic device in Mr. Klotz’s bin
Make sure your device is on silent
What are the units for molarity?
What are the units between molality?
When is molality used instead of molarity?

5. Objectives Today I will be able to:
Apply molarity, molality, mole fraction and dilution calculations to a quiz
Construct a solubility curve for a compound

6. Homework
Finish constructing the solubility curve.

7. Agenda Warm – Up Concentration Quz Construct a Solubility Curve
Exit Ticket

8. Concentration Quiz
When you complete your quiz, bring it up to Mr. Klotz. You may work on other homework or sit silently until everyone is finished

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

10. Solubility of Liquids
What effect does increasing the temperature have on the solubility of a liquid?
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

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