Question: Calculate the percent ionization of the in a 0.10 m solution?

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% . The percent ionization of a weak acid and HA is defined as the ratio of the equilibrium h3o+ concentration to the initial ha concentration multiplied by 100%.
