How To Calculate Percent Ionization?

Percent ionization = ( frac{text{amount ionized}}{text{initial amount}} times 100 )

For a weak acid: ( % text{ ionization} = frac{[H^+]}{[HA]_0} times 100 )

For a weak base: ( % text{ ionization} = frac{[OH^-]}{[B]_0} times 100 )

Find the equilibrium ion concentration from an ICE table or equilibrium calculation

Divide the equilibrium ion concentration by the initial concentration

Multiply by 100 to get percent ionization
