WebJul 20, 2024 · pKa(HA) + pKb(A −) = pKw. Thus the product of the acid constant for a weak acid and the base constant for the conjugate base must be Kw, and the sum of p Ka and p Kb for a conjugate acid-base pair is 14. Equation 14.7.4 or 14.7.8 enables us to calculate the base constant of a conjugate base from the acid constant of the acid, and vice versa.
