Formulas:
Ka = [H+][A-] / [HA]
Kb = [BH+][OH-] / [B]
Ka x Kb = Kw = 10^-14
Understanding Ka and Kb
Ka (acid dissociation constant) and Kb (base dissociation constant) quantify the strength of weak acids and bases. Larger Ka values indicate stronger acids, while larger Kb values indicate stronger bases. These constants can be determined experimentally by measuring the pH of a solution with known concentration.
