Chemistry 12:  Unit 5 # 1-5.  Lab 20H part I (calculate the pH at every second interval - 0.00, 10.00, 20.00, 24.00, etc).  Show your calculations clearly.  Plot the graph if you get time.  No typical lab set-up needed for 20H.

Food Hamper items - we need more to help out our families over the Holiday Season.

Finally, your Term 2 Grades, including the Acid Base test.

Chemistry 12:  Please bring some food items for the two families that we are taking care of.  Today we learned about buffers (Section 4.19) and I assigned # 131 - 134, which is due Monday.  Lab 20G was handed in today.  Make sure that U4 # 108 - 118 from Thursday is finished too.  Acid Base unit test on Tuesday.




Chemistry 12:  Due Friday is Lab 20G [Calculations for parts I to IV, and Follow-up Questions # 1-3. No conclusion yet].  We also did Unit 4 # 108 - 118 (practice with indicators) and I had meant for these to be done for Friday, but forgot to remind you:).  You were given a practice test, but this will be due on Tuesday.

We are also collecting food for the annual Christmas Family Hamper.  We are in charge of outfitting two families with items for their fridge/pantry.   These items are due next Friday.

Thanks for your focus and attention to detail as we head into the last week before Christmas break. On Tuesday we will have an Acids and Bases test.  There are only 3 weeks left of our course after the Christmas break!
