These notes can be used while reading Chapter 18-3, pages 567-576. Try the sample problems given and be sure to ask questions in class if you get stuck anywhere or would like clarification on anything.
This power point describes Acid/Base Equilibria and demonstrates how to solve for the pH of a weak acid or weak base.
A sample problem worked out in steps describing how to determine the percent ionization of an acidic solution.
This video demonstrates how to determine the [H+] of a weak acid in order to determine the pH using the acid dissociation constant as a starting point.
