We argued qualitatively in,Suppose in the general case we have a weak acid HA whose conjugate base is A,and \(\text{ A}^{-} + \text{ H}_{\text{2}}\text{O}\rightleftharpoons\) \(\text{HA} + \text{ OH}^{-}\) in which A,To the first of these equilibria we can apply the equilibrium constant,\[K_{a}\text{(HA)}=\frac{[\text{ H}_{\text{3}}\text{O}^{\text{+}}][\text{ A}^{-}\text{ }]}{[\text{ HA }]}\],while to the second we can apply the equilibrium constant,\[K_{b}\text{(A}^{-}\text{)}=\frac{[\text{ HA }][\text{ OH}^{-}\text{ }]}{[\text{ A}^{-}\text{ }]\text{ }}\].Multiplying these two constants together, we obtain a simple relationship between them.\(\begin{align}K_{a}\text{(HA)}\times K_{b}\text{(A}^{-}\text{)}=\frac{[\text{H}_{\text{3}}\text{O}^{\text{+}}][\text{A}^{-}]}{[\text{HA }]}\times \frac{[\text{HA}][\text{OH}^{-}]}{[\text{A}^{-}]}\\\\\text{ }=[\text{H}_{\text{3}}\text{O}^{\text{+}}][\text{ OH}^{-}]\end{align}\),\[K_{a}\text{(HA)}\times K_{b}\text{(A}^{-}\text{)}=K_{w}\label{6}\],If we divide both sides of this equation by the units and take negative logarithms of both sides, we obtain,\[\begin{align}\text{p}K_{a}=-\text{log}\frac{K_{a}\text{(HA)}}{\text{mol L}^{-\text{1}}}-\text{log}\frac{K_{b}\text{(A}^{-}\text{)}}{\text{mol L}^{-\text{1}}}\\\text{ }\\\text{ }=-\text{log}\frac{\text{10}^{-\text{14}}\text{ mol}^{\text{2}}\text{ L}^{-\text{2}}}{\text{mol}^{\text{2}}\text{ L}^{-2}}\end{align}\],\[\text{p}K_{a}\left(\text{HA}\right) + \text{ }\text{p}K_{b}\text{(A}^{-}\text{)}=\text{p}K_{w}\label{10}\],Thus the product of the acid constant for a weak acid and the base constant for the conjugate base must be,Equation \(\ref{6}\) or \(\ref{10}\) enables us to calculate the base constant of a conjugate base from the acid constant of the acid, and vice versa.
