Chemistry 12: Equilibrium Unit- Jan 21-Feb 13

Thurs Feb 13:
We covered Bronsted-Lowry Theory, Water equilibrium,  pH of strong acids and strong bases.
homework:
No homework weekend.  If you want to get ahead in your work:
Do B-L Exercise in notes, p. 2,   pH and Kw textbook questions listed on p. 5 of pkg.

Tues Feb 11:
Equilibrium Test written
homework:
Finish Acid-Base Neutralization questions #1-4 on p. 2 of new package.

Fri Feb 7:
We took up Ksp questions, and started Acids and Bases package (p. 1-2)
homework:
Prepare for Equilibrium Test next class.  You will need a standard Math calculator.

Wed Feb 5:
We covered p. 14 on predicting precipitation using Ksp.  We also took up the Le Chatelier lab.  Kc Lab quiz was written..
homework:
Do Ksp problems p. 15  #9, 10, 11 (tricky),  13,  14 on precipitation prediction.

Mon Feb 3:
We did the Kc experiment and submitted our data.  Le Chatelier labs were returned.
homework:
Complete the Kc lab calculations to prepare for the lab quiz next class.
Do Ksp problems p. 15  #3, 6, 7, 8 on the common ion effect

Thurs Jan 30:
We went over p.9-10 on making approximations,  went over the theory of the Kc lab, and covered most of Ksp (calculating Ksp, molar solubility and the Common Ion effect)
homework:
Do textbook p.  476  #7,8 on approximations,  Do Ksp problems p. 15 of notes #1b,  2b,  #4 at a minimum.  We will do Kc experiment next class.

Tues Jan 28:
We did the Le Chatelier lab and lab quiz.
homework:
Check your equilibrium problems (p. 11,  solutions are on this site).  Read p. 9 in the notes and use the website notes to fill in example problem on p. 10 (p.  11 on on-line notes).

Fri Jan 25:
We took up the K homework,  covered problems on p. 7-8 of notes and briefly discussed the Le Chatelier lab coming up.
homework:
Be ready for the Le Chatelier lab quiz next class.
Do problems from p. 11 #2-10

Wed Jan 23:
We took up Le Chatelier graphs (part II of p. 5), then we covered Equilibrium Law and K.  We did one problem on p. 7
homework:
Do K textbook questions listed on p. 6 of notes.

Mon Jan 21:
We took up the rates test,  worked on the Le Chatelier Worksheet of notes ( p 5)  part I: predicting direction of shift and part II:  making conc. vs. time graphs for questions #1-4.  This is the topic of the first lab and lab quiz next week.  We took up part I. of the worksheet and will take up the graphs next period
homework:
p. 5 worksheet parts I and II

Wed Jan 15:
We covered Le Chatelier's Principle.
homework:
Review for rates  unit test on Tuesday Jan 14 (this date has been changed)

Fri Jan 10:
I passed back the iodine clock labs.  We started a new unit: Equilibrium with an intro in the new notes. (p.1-demo on p. 3)
homework:
Review for rates  unit test on Tuesday Jan 14 (this date has been changed)
