Concept Review

  1. Equilibrium constant expressions from balanced equations.

  2. Equilibrium shifting due to small or large K.

  3. Getting K from known equilibrium concentrations.

  4. Using an equilibrium chart
    • initial moles
    • initial concentration
    • complete reaction
    • equilibrium concentrations

  5. Getting K from one known equilibrium concentration and the balanced equation.

  6. Calculate equilibrium concentrations from the initial conditions and K.
    • K around one (between 10-4 and 104)
    • Small K (less than 10-4)
    • Large K (greater than 104)

  7. Identifying conjugate acids and bases.

  8. Autoionization of water and Kw.

  9. pH, pOH, and pKa.

  10. Finding equilibrium concentrations and pH in weak acid solutions.

  11. Common ion problems.

  12. Solubility products - Ions in equilibrium with their solid and Ksp.

  13. Titration of a strong acid with a strong base.

  14. Titration of a weak acid with a strong base.

  15. The Henderson-Hasselbach equation.

  16. Buffers
