Learning Outcomes for UNIT 2

Each student should have a good grasp of the following learning outcomes for unit 2. Unit 2 is assessed on Exam 2 which is on Tuesday 3/6/12 from 7-9 PM. Read the bulleted points and self assess yourself on how well you know the topic.

Students will be able to...

  1. Write a complete mass action expression and know the conditions in which it is equal to Q and K.
  2. Calculate the concentration of all species at equilibrium.
  3. Know the difference between Kp and Kc and know the mathematical relationship between them.
  4. Set up and solve an ICE table.
  5. Calculate the value of the equilibrium constant at a new temperature. 
  6. Show a complete understanding of Le Chatelier's principle. 
  7. Predict the direction of a reaction after an applied stress. Stresses include pressure changes, concentration changes, increase or decrease in temperature, and global volume change.
  8. Convert ΔG to Q and/or convert ΔG° to K and vice versa.a
  9. Determine new values for K when combining multiple reactions.
  10. Determine the pH of a strong acid or strong base solution.
  11. Determine the pH of a weak acid or weak base solution.
  12. Calculate the percent ionization of a weak acid or weak base solution.
  13. Know the mathematical relationship between Ka and Kb of a conjugate pair.
  14. Determine the pH of the solution made from the salt of a weak acid or the salt of a weak base.
  15. Calculate the concentration of hydrogen ion, hydroxide ion, plus the pH and pOH of a given aqueous solution.
  16. Know the definition of neutral water and the consequences of that definition.
  17. Know the value Kw at 25°C.
  18. Calculate the pH of a buffer.
  19. Calculate the pH of a buffer after the addition of strong acid or strong base.
  20. Fully understand the way an acid/base indicator works. This includes predicting correct colors and color-combinations for a given indicator at a given pH.b
  21. Determine the appropriate indicator for an acid/base titration.
  22. Utilize and interpret a fraction of species diagram.
  23. Determine the equivalence point pH of any titration.
  24. Utilize can interpret a titration curve plot ( aka: a pH curve). 

a. This corresponds to sections 10.10 and 10.11 in your book.
b. You don't have to memorize the chart of indicator colors and pH ranges. The 2 basic colors and Ka will be given in the problem.
