Chapter 9, Problem 9.34PP

Identify the acid and base on the reactant side of the following equations and identify their conjugate species on the product side:

1. a. ${\text{H}}_{\text{3}}{\text{PO}}_{\text{4}}(aq)+{\text{H}}_{\text{2}}\text{O}(l)\rightleftharpoons {\text{H}}_{\text{3}}{\text{O}}^{\text{+}}(aq)+{\text{H}}_{\text{2}}{\text{PO}}_{\text{4}}^{-}(aq)$
2. b. ${\text{CO}}_{\text{3}}^{\text{2-}}\text{(}aq{\text{)+H}}_{\text{2}}\text{O(}l\text{)}\rightleftharpoons {\text{OH}}^{\text{-}}\text{(}aq{\text{)+HCO}}_{\text{3}}^{\text{-}}\text{(}aq\text{)}$
3. c. ${\text{H}}_{\text{3}}{\text{PO}}_{\text{4}}\text{(}aq{\text{)+NH}}_{\text{3}}\text{(}aq\text{)}\rightleftharpoons {\text{NH}}_4^{+}\text{(}aq{\text{)+H}}_{\text{2}}{\text{PO}}_{\text{4}}^{\text{-}}\text{(}aq\text{)}$
