Calculate the percent ionization as a function of the initial acid concentration for any case to confirm what you found in EC1. That is, use variables to represent the initial concentration and Ka and solve for percent ionization.

Weak Acid
Concentration, M	pH	Ka
0.100	2.87	1.84x10-5
0.0100	3.42	1.50x10-5
0.00100	4.13	2.12x10-3
