Chapter 9, Problem 9.52P

Label the conjugate acid-base pairs in each equation.

a. ${\text{CI(aq) + HSO}}_{\text{4}}{}^{-}\text{(aq)}\rightleftarrows {\text{ HCI(aq) + SO}}_4{}^{2-}\left(\text{aq}\right)$

b. ${\text{HPO}}_4^{2-}{\text{(aq) + OH}}^{-}\text{(aq) }\rightleftarrows {\text{ PO}}_4{}^{3-}{\text{(aq) +H}}_2\text{O}\left(\text{I}\right)$

C. ${\text{NH}}_3\text{(g) + HF(g) }\rightleftarrows {\text{ NH}}_4{}^{+}{\text{(aq) + H}}^{-}\text{(aq)}$
