General Chemistry II

Dr. M. J. Wieder

Topic: Buffers, Ksp, and Complex Ion Equilibrium 

The student should be able to:

  1. Recognize the components of a buffer system.
  2. State the purpose of a buffer system and explain how it accomplishes that goal.
  3. Determine the pH of a buffer system given relevant concentration and ionization constant data.
  4. State the purpose of an acid-base titration.
  5. Interpret titration curves for acid-base titrations.
  6. Explain how acid-base indicators function.
  7. Predict in which form an acid-base indicator will exist given ionization constant and concentration data.
  8. Determine Ksp values given appropriate solubility data.
  9. Determine solubilities of relatively insoluble inorganic salts from Ksp data.
  10. Predict when a relatively insoluble salt will precipitate given appropriate concentration and Ksp data.
  11. Write mass law equations for Kformation and Kdissociation (Kinstability) for complex ions in aqueous medium.
  12. Determine Kformation or Kinstability constants from suitable concentration data for complex ions.
