WebAug 14, 2024 · The magnitude of the equilibrium constant for an ionization reaction can be used to determine the relative strengths of acids and bases. For example, the general equation for the ionization of a weak acid in water, where HA is the parent acid and A− is its conjugate base, is as follows: HA ( aq) + H2O ( l) ⇌ H3O + ( aq) + A − ( aq) The ... WebThe calculation of pH becomes straightforward. For basic solutions, you have the concentration of the base, thus, the concentration of the hydroxide ions OH-. You can calculate pOH. Based on equilibrium concentrations of H+ and OH− in water (above), pH and pOH are related by the following equation, which is true for any aqueous solution.
