Chemistry- Equilibrium and Acid/Base Test Review, May 21, 2009

Included below is a sampling of some of the material that will be covered in the test. Use this package to aid in your studying. This is not fully comprehensive- use your notes and homework problems as well.

Equilibrium Test Review

After you have completed the review, you can check y our answers with the key below:

Equilibrium Test Review Answers

Chemistry, Ka and Kb Constants- May 20, 2009

Common Ion Effect

When dealing with weak acids and weak bases, you also might have to deal with the “common ion effect”. This is when you add a salt to a weak acid or base that contains one of the ions present in the acid or base. To be able to use the same process to solve for pH when this occurs, all you need to change are your “start” numbers. Add the molarity of the ion, which comes from the salt, and then solve the K_a or K_b equation as you did earlier.

Ex.Find the pH of a solution formed by dissolving 0.100 mol of CH₃COOH with a K_a of 1.8×10^-8 and 0.200 mol of NaCH₃COO in a total volume of 1.00 L.

For practice, try page 592 #8-10 and page 595 #12-16 from the chemistry text.

Chemistry Test- This Friday, May 22, 2009

This is just a reminder that there will be a chemistry test on Friday, May 22, 2009. This date was chosen to accommodate those who are participating in the track and field events during the week. The material covered on this test includes chapter 13 and 14 in their entirety (equilibrium,Le Chatelier’s Principle, properties of acids and bases). If you have questions, please bring them to class prior to Friday.
