Titrations and Buffers Test

1.  Hand in the ch17 WS questions, corrections/reflection for sections 1-3.

2.  Test

3.  Science Fair “bootcamp” – What is an independent variable? dependent variable?  What is the marking criteria?  What should I look for in a good project?  We will be helping to judge/give feedback to the Science 8/8H and 9/10H classes next week.


Intro to Ksp

1. Hand in Lab 20G.

2.  2012 Chem12AP Free Response Question #1 – Challenge.  How many can you answer correctly in 15 minutes?

3.  Intro to Ksp – Fill in the study guide.  Read and take notes from sections 17.4-end.

Law of Conservation

1.  Any Q’s?

2.  Activity:  proving the Law of Conservation – true or not?

Activity – prove the Law of Conservation

3.  I will be able to balance chemical reactions.  See class notes here:

Law of Conservation

4. Read sec. VI.1- VI.3 and do Q # 1, 4, and 7-51 (odd numbers)

5.  Study!!!

Moles Test #2 next class on section V.4-V.6.  Bring a scientific calculator.

Test outline:  Percent composition and Empirical and Molecular Formulas will comprise 50% of the test score.  Molarity and dilutions will comprise the other 50% of the test score.  The test will be all written.  Show your work!  Draw mole wheels!

Molarity and Dilutions Day 2

1.  I will be able to calculate the new molarity when a solution is diluted.

2.  Finish reading section V.6

3.  Do:  Review Questions #95-102 (odd #s)

Moles Test #2 on sections V.4-V.6 on Friday Jan 23 and Mon Jan 26.

Just for fun video about the 5 Most Dangerous Chemicals in the World:

Lab 20G Parts 3-5

1.  From Parts 1 and 2, use the molarity of NaOH you calculated to determine the molar mass, Ka, and [acid] for parts 3-5.  Show your calculations neatly and clearly!

2. For Part 5, your group needs to write out full lab (ie. purpose, materials, procedure you used, etc…)

3.  Finish reading sections 17.1-17.3 and do practice textbook questions.

4.  Do:  Chapter 17 Review WS  # 11, 12, 15, 18, 19, 21 and mc #22-28
