% Ionization [ENDORSED]

[welcometochillis]

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

[Nicole Nikolov 1K]

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

[Thuy-Anh Bui 1I]

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

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