Chapter 14, Problem 4PP

Cadmium reacts with nickel(II) nitrate according to the following equation:

$\text{Cd}\left(s\right)+\text{Ni}{\left({\text{NO}}_{\text{3}}\right)}_2\left(aq\right)\to \text{Cd}{\left({\text{NO}}_{\text{3}}\right)}_2\left(aq\right)+\text{Ni}\left(s\right)$

(a) Write equations to represent the oxidation and reduction half-reactions.

(b) Determine the oxidizing and reducing agents.

(c) Draw a picture like the one given in the example to show the components of this voltaic cell. Label the components A, B, C, D, and E and answer the same questions as in the example.
