Equilibrium constant for the dissociation of a weak acid, K a Remember, weak acids only slightly dissociate: HB ⇔ H+ (aq) + B-(aq) The products are a proton and a conjugate base. Since the reactants are in equilibrium with the products, we can write an equilibrium expression: K a = [H +][B-] ----- [HB] K
