Reading Preparation
Textbook assignment: Read Kotz and Triechel, Chemistry and Chemical Reactivity Chapter 17: Section 4.
Study Notes
- 17.4 Precipitation reactions occur when the cation of the base and the anion of the acid are insoluble. The solubility product constant Ksp is used to indicate the concentrations when a precipitation reaction comes to equilibrium. (The solubility of the salt is the amount present at saturation). Addition of the common ion to a solution containing a precipitate will generally cause more precipitate to form by lowering the salt solutibility.
Key Formula

Study Activity
Videos for Chapter 17: Principles of Chemical Reactivity: Other Aspects of Aqueous Equilibri
Review the Videos at Thinkwell Video Lessons.
- Under "EQUILIBRIUM IN AQUEOUS SOLUTIONS"
- Solubility Equilibria
- The Solubility Product Constant
- Solubility and the Common Ion Effect
- The Effects of pH on Solubility
- Solubility Equilibria
Follow the instructions at the Chem Collective to perform the Virtual Lab: Determine pKa and Concentration of a Protein in Solution If you have not used the Chem Collective before, watch the introductory video and support information.
- Read the pKa and Weak Acid Problem description.
- Use the equipment, acids, bases, and distilled water at your disposal, along with the protein and HCl solution, to determine the pKa of the protein and determine the pH for a solution where the protein ion/protein acid ratio is 0.75?
- Carry out the instrucctions to create a 100mL solution and test that it actually works.
Chat Preparation Activities
- Essay question: The Moodle forum for the session will assign a specific study question for you to prepare for chat. You need to read this question and post your answer before chat starts for this session.
- Mastery Exercise: The Moodle Mastery exercise for the chapter will contain sections related to our chat topic. Try to complete these before the chat starts, so that you can ask questions.
