Percent Ionization Brief Description: Visualize the percent ionization of an acetic acid solution Explanation of Experiment: Strong acids ionize completely when they are dissolved in water, while weak acids ionize only slightly. As an example, glacial acetic acid has an acid dissociation constant of 1.75 x 10-5. A 10 M solution of acetic acid has a percent ionization of only 0.132 %. However, a 0.10 M solution has a percent ionization of 1.32 %. In this demonstration, the relative ionization of
