Textbook Problem

For each of the following aqueous reactions, identify the acid, the base, the conjugate base, and the conjugate acid.

a. $\text{Al}{\left({\text{H}}_{\text{2}}\text{O}\right)}_6{}^{3+}+{\text{H}}_{\text{2}}\text{O}\rightleftharpoons {\text{H}}_{\text{3}}{\text{O}}^{+}+\text{Al}{\left({\text{H}}_{\text{2}}\text{O}\right)}_5{\left(\text{OH}\right)}^{2+}$

b. ${\text{H}}_{\text{2}}\text{O}\text{+}{\text{HONH}}_{\text{3}}{}^{\text{+}}\rightleftharpoons {\text{HONH}}_2+{\text{H}}_{\text{3}}{\text{O}}^{+}$

c. $\text{HOCl}\text{+}{\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NH}}_{\text{2}}\rightleftharpoons {\text{OCl}}^{-}+{\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NH}}_3{}^{+}$
