In Section 8.3 an equation was derived for the exact treatment of HA/NaA-type buffers. What would be the expression for \(\mathrm{B} / \mathrm{BHCl}\)-type buffers stated in terms of \(\mathrm{K}_{\mathrm{b}}\), \(\left[\mathrm{OH}^{-}ight],[\mathrm{B}]\), and \(\left[\mathrm{BH}^{+}ight]\)? Would it be necessary to use this exact expression to solve for the \(\mathrm{pH}\) of a solution containing \(1.0 \times 10^{-4} \mathrm{M} \mathrm{HONH}_{2}\) and \(1.0 \times 10^{-5} \mathrm{M}\) \(\mathrm{HONH}_{3} \mathrm{Cl}\) ? Explain.
