When it comes to calculating the percent ionization or percent association, it's important to remember that weak bases also represent weak electrolytes that only partially ionized or dissociate into aqueous ions. Because of this fact, weak basis ionize less than 100%.
Strong bases, on the other hand, they represent strong electrolytes and therefore ionize completely. So they would ionize 100%. If we wanted to determine the percent ionization or percent association for a weak base, we utilize the following formula.
Here we're going to say percent ionization and percent dissociation equals the concentration of hydroxide ion at equilibrium divided by the initial concentration of my weak base times 100. Utilizing this formula will be able to determine the percent ionization of any given weak base.
Percent ionization = Concentration of hydroxide ion at equilibrium Initial concentration of weak base × 100
