Chemistry, Ka and Kb Constants- May 20, 2009

Common Ion Effect

When dealing with weak acids and weak bases, you also might have to deal with the “common ion effect”. This is when you add a salt to a weak acid or base that contains one of the ions present in the acid or base. To be able to use the same process to solve for pH when this occurs, all you need to change are your “start” numbers. Add the molarity of the ion, which comes from the salt, and then solve the Ka or Kb equation as you did earlier.

Ex.Find the pH of a solution formed by dissolving 0.100 mol of CH3COOH with a Ka of 1.8×10-8 and 0.200 mol of NaCH3COO in a total volume of 1.00 L.

Picture 1

For practice, try page 592 #8-10 and page 595 #12-16 from the chemistry text.
