Percentage Ionization

Postby Chloe Thorpe 1J » Wed Jan 16, 2019 8:24 pm

Someone in lecture asked if, for example, the 1.3% ionization meant that only 1.3% of the acid reacted with the water. Is this correct? I didn't catch the answer.

Yes. Percentage ionization is the amount of the weak acid that deprotonated (gave away a H+ to form H3O+).

Yes because % ionization relates to the amount of acid that reacts with water to form H30+.

Elaborating on the previous replies, since percent ionization for acids are [concentration of H+ at equilibrium][/concentration of HA initial] multiplied by 100, it is the amount of the original acid that has dissociated in percent.
