  1. Common Ion Effect

  2. Definition • Shift in equilibrium that occurs when we add an ion that is a component of an equilibrium reaction

  3. Example • Suppose that we add .100 mole of sodium acetate, NaC2H3O2 , to 1 L of .100 M solution of acetic acid, HC2H3O2 . What is the pH of the solution?

  4. Example • Calculate the fluoride concentration and pH of a solution containing .10 mole of HCl and .20 mole of HF in a liter of solution.

  5. Example • Calculate the % dissociation of HF in a solution containing 1.0M HF and 1.0M NaF.
