  Overview of Chapter Guide Four

Chapter 15 revisits solubility from CH 221, but we will examine it in considerable more detail using our understanding of equilibrium. We shall learn about the solubility product constants, Ksp, and know how it relates to a substance's solubility in solution. We shall be able to use Ksp to determine how much solute will dissolve in a given amount of solvent. We shall also be able to use solubility to separate mixtures, and we will use the common ion effect to manipulate solubility. We shall also look at the important concepts of Lewis acids and bases to see how this acid base theory can be extended to almost any type of reaction.

For a complete list of important concepts in Chapter 15, see the Chapter 15 Study Guide.

  Resources for Chapter Guide Four

For this module, you should read Chapter 15 in your textbook.

The following screencasts and Complete Lectures might prove useful to you as you study this chapter.

The Chapter Fifteen lecture notes which accompany this lesson will be helpful when going through this section. These are Web versions of the lecture notes used in the "normal" CH 223 class and should let you see what is important in this chapter. You can also view the Lecture Notes in presentation software: Keynote, PowerPoint

A variety of handouts are available from Chapter Fifteen. Feel free to explore all of them or just the ones which give you difficulty.

Once you have mastered the concepts listed above, check out the Chapter Fifteen Concept Guide for a series of worked problems relating to this module. They will help you to ensure the mastery of the knowledge from this section.

Finally, test yourself (and get extra-credit in the bargain!) on the following chemistry concepts. If you get 9 out of 10 correct (or some multiple thereof), submit the information to receive extra credit.

  1. Slightly Soluble Salts
  2. The Common Ion Effect
  3. Predicting Precipitation

  Practice the Concepts of Chapter Guide Four

Complete problem set #4 to further explore the ideas of this chapter. Problem set #4 covers several questions from Chapter 15, and it can be found here. We will discuss problems like these during recitation, so come prepared to ask and answer questions.

For additional practice, try completing practice problem set #4 (with answers included at the end) and/orthe non-assigned problems in Chapter 15. Answers to many of those problems are listed in the back of your textbook.

If you need assistance on these problems, you have several options. You can visit the AVID / Learning Success Center located above the MHCC library on the Mt. Hood Community College campus; they have tutors available to help you with your chemistry homework. You can also contact me if you have any questions.

This sample Quiz #4 (with answers at the end) which was given during a previous year's CH 223 class will help you understand the kind of questions that will be asked on the quiz.

You can also test your mastery of the subject matter by trying the self quiz for Chapter 15. This is an ungraded quiz that you can use to gauge your comfort level with these concepts.
