Description:

Learning Targets:

I can explain how an acid can be weak in terms of "dissociation equilibrium".
I can write the the acid dissociation constant, K_a, for a weak acid.
I can use an ICE table to solve for [H⁺] or K_a for an aqueous solution of a weak acid.
I can calculate the pH of a weak acid using an ICE table.

Textbook Notes: Calculating the Ka and [H+] of Weak Acids

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.

Power Point - Acid/Base Equilibria

This power point describes Acid/Base Equilibria and demonstrates how to solve for the pH of a weak acid or weak base.

Percent Ionization Notes

A sample problem worked out in steps describing how to determine the percent ionization of an acidic solution.

Determining the pH of a Weak Acid from the Ka

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.
