Answer
The percent ionization of an acid is a number that quantifies the amount of acid molecules that ionizes compared to the total amount of acid molecules added initially.
Equation:
$$Percent \space ionizaition = \frac{concentration \space of \space ionized \space acid}{initial \space concentration \space of \space acid} \times 100\%$$
Or basically:
$$Percet \space ionization = \frac{[H_3O^+]_{equi}}{[HA]_{initial}} \times 100\%$$
The percent ionization decreases when the concentration of the weak acid increases, and increases when the same decreases.
