### % Ionization

IS percent ionization measured by dividing the change in concentration of initial concentration or is it measured by dividing the final by the initial????

### Re: % Ionization

To find percent ionization, you should divide the hydrogen concentration at equilibrium by the initial concentration of the acid, and multiply by 100.

### Re: % Ionization  [ENDORSED]

For a given equation: acid + H2O ⇌ H3O+ + conjugate base
% ionization/dissociation = ([equilibrium concentration of H3O+] / [initial concentration of acid]) x 100

For a given equation: base + H2O ⇌ OH- + conjugate acid
% ionization/dissociation = ([equilibrium concentration of OH-] / [initial concentration of base]) x 100

So in general:
% ionization/dissociation = ([equilibrium concentration of (ion)] / [initial concentration of (what was ionized)]) x 100

### Re: % Ionization

Is the hydrogen proton concentration the same as the conjugate base concentration for an acid?
