Learning Outcomes for UNIT 3

Each student should have a good grasp of the following learning outcomes for unit 3. Unit 3 is assessed on Exam 3 which is on Tuesday 4/10/12 from 7-9 PM. Read the numbered points and self assess yourself on how well you know the topic.

Students will be able to...

  1. Calculate molar solubility from \(K_{\rm sp}\).
  2. Calculate \(K_{\rm sp}\) from solubility data.
  3. Rank salts in order of solubility according to \(K_{\rm sp}\) values.
  4. Calculate remaining ion concentration in solution for a selective precipitation.
  5. Calculate concentration of the associated species for complex ion equilibria.
  6. Know what attributes are associated with a good ligand.
  7. Understand the chemistry involved in dissolving precipitates.
  8. Assign oxidation numbers to the various elements in a formula.
  9. Completely balance a redox reaction in acid.
  10. Identify the reducing agent and oxidizing agent in a redox reaction.
