Consider only the species (at standard conditions)

\[\mathrm{Na}^{+}, \mathrm{Cl}^{-}, \mathrm{Ag}^{+}, \mathrm{Ag}, \mathrm{Zn}^{2+}, \mathrm{Zn} \text {, and } \mathrm{Pb}\]

in answering the following questions. Give reasons for your answers. (Use data from Table 11.1.)

a. Which is the strongest oxidizing agent?

b. Which is the strongest reducing agent?

c. Which species can be oxidized by \(\mathrm{SO}_{4}{ }^{2-}(a q)\) in acid?

d. Which species can be reduced by \(\mathrm{Al}(s)\) ?
