Chapter 14.2, Problem 14.7QAP

Identify the reactant that is a Bronsted-Lowry acid and the reactant that is a Bronsted-Lowry base in each of the following

a $\text{H1}\left(aq\right)+{\text{H}}_2\text{O}\left(l\right)\to {\text{I}}^{-}\left(aq\right)+{\text{ H}}_{\text{3}}\text{O}\left(aq\right)$
b ${\text{F}}^{-}\left(aq\right)+{\text{H}}_2\text{O}\left(l\right)\rightleftharpoons \text{HF}\left(aq\right)+{\text{OH}}^{-}\left(aq\right)$
c. ${\text{H}}_{\text{2}}\text{S}\left(aq\right)+{\text{CH}}_{\text{3}}—{\text{CH}}_{\text{2}}—{\text{NH}}_{\text{2}}\left(aq\right)\rightleftharpoons {\text{HS}}^{-}\left(aq\right)+{\text{CH}}_{\text{3}}—{\text{CH}}_2—{\text{NH}}_{\text{3}}{}^{+}(aq)$
