1 November 18, 2013 Once you’re in, you’re in
November 18, 2013 Once you’re in, you’re in. When the bell rings, electronics and headphones away working on the DO NOW. HAVE OUT ON YOUR DESK YOUR VOCAB HW. TURN IN ANY LATE STEM PROJECT ASSIGNMENTS AND ANY LATE HW. DO NOW: Have out your lab pre-work, something to write with, and your solubility notes. Everything else (including food and drink) need to be under the apron hooks. If you finished your lab pre-work be prepared for it to be check. If you have not it must be complete to start the lab. Start that now.

2 Solutions Lab 30 minutes to complete
If you finish early work on your solutions curve handout from last week (back of the video guide)

3 Tutoring Thursday afterschool in 710 (2:30-3:30pm)

4 Homework Lab post questions ** HW assignment #12** **graded

5 Notebook Check 11-22-13 Stoichiometry Island Flow Chart
Anticipation Guide Solutions (just the guide, not the reading) Pink Solutions Vocabulary (both parts)

6 Week of 11-18-13 November 18: Solubility Lab Solubility Quiz
Finish Solubility HW: Assignment #12, Finish lab post-questions November 19: Energy Change and ThermoChemistry HW: Study for Solutions Test, vocab column #1 November 20: Solutions Test , Notebook Check Energy Change and ThermoChemistry HW: Assignment #13, Vocab column #2 November 21: Energy and Thermochemistry Thermochem quiz HW: Assignment #14, Vocab column #3 November 22: Solutions Test , Notebook Check HW: ClEvR Report due Tuesday

7 Objectives SWBAT Infer the quantitative nature of a solution (molarity and dilution) Summarize properties of solutions Interpret Solutions diagrams Explain the solution process

8 Colligative Properties of Solutions
Colligative properties are properties that depend only on the number of solute particles in solution and not on the nature of the solute particles. Vapor Pressure Lowering Boiling Point Elevation Freezing Point Depression Osmotic Pressure

9 FOLDABLE 4 squares Colligative Properties
Vapor Pressure Lowering Vapor Pressure Lowering is due to the number of solute particles in solution The greater the number of solute particles in a solvent, the lower the resulting vapor pressure. Boiling Point Elevation Temperature difference between as solution’s boiling point and a pure solvent’s boiling point The greater the number of solute particles in the solution, the greater the boiling point elevation.

10 Colligative Properties
Freezing Point Depression The difference in temperature between its freezing point and the freezing point of its pure solvent. The freezing point of a solution is always lower than that of a pure solvent. Depends on the number of solute particles in a given volume of solution. Osmotic Pressure Amount of additional pressure caused by the water molecules that moved into the solution. Depends on the number of solute particles in a given volume of solution.
