Chapter 17, Problem 16QAP

Consider a salt bridge voltaic cell represented by the following reaction    ${\text{MnO}}_4{}^{-}\left(aq\right)+8{\text{H}}^{+}\left(aq\right)+5{\text{Fe}}^{2+}\left(aq\right)\to {\text{Mn}}^{2+}\left(aq\right)+5{\text{Fe}}^{3+}\left(aq\right)+4{\text{H}}_2\text{O}$
(a) What is the direction of the electrons in the external circuit?
(b) What electrode can be used at the anode?
(c) What is the reaction occurring at the cathode?
