Chapter 14, Problem 31E

For each reaction, identify the Brønsted-Lowry acid, the Brønsted-Lowry base, the conjugate acid, and the conjugate base.

a. $\text{HBr}(aq)+{\text{H}}_{\text{2}}\text{O}(l)\to {\text{H}}_{\text{3}}{\text{O}}^{\text{+}}(aq)+{\text{Br}}^{\text{-}}(aq)$

b. ${\text{NH}}_3(aq)+{\text{H}}_{\text{2}}\text{O}(l)\rightleftharpoons {\text{NH}}_4(aq)+{\text{OH}}^{-}(aq)$

c. ${\text{HNO}}_3(aq)+{\text{H}}_{\text{2}}\text{O}(l)\to {\text{H}}_{\text{3}}\text{O}(aq)+{\text{NO}}_3{}^{-}(aq)$

d. ${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{N}(aq)+{\text{H}}_{\text{2}}\text{O}(l)\rightleftharpoons {\text{C}}_{\text{2}}{\text{H}}_{\text{5}}{\text{NH}}^{+}(aq)+{\text{OH}}^{-}(aq)$
