% Ionization

How do you calculate the percent ionization of an acid?

After you do the ICE box method and find the equilibrium concentrations, you divide the equilibrium concentration of the conjugate acid or base by the initial concentration of the acid or base given and multiply that by 100. For example, if the chemical reaction was CH3COOH + H2O --> CH3COO- + H3O+, then the percent ionization would be [CH3COO-]/[CH3COOH] times 100.

Percent ionization is related to the amount of weak acid that exists as ions at a specific concentration.

Percent ionization formula : [H+] / [HA] x 100%

Hope this helps.

To calculate the percent ionization, divide the conjugate acid or base equilibrium molarity by the acid or base initial molarity.
