Acid-base Equilibria Important Equations: Self-ionization of water: H2O H+ + OH- Kw = [H+][OH-] = 1.0 x 10-14 Acid dissociation: HA + H2O H3O+ + A- HA H+ + A- Base dissociation (e.g. NaOH, KOH): BOH B+ + OH- Base hydrolysis (e.g., NH3): B + H2O BH+ + OH-
Acid-base Equilibria (cont’d) Hydrolysis of the conjugate base of an acid: A- + H2O HA + OH- Note that: = [H+][OH-] = Kw In a buffer system:
