Problem Details

Given the overall redox reaction: Fe2+(aq) + Ce4+(aq) → Fe3+(aq) + Ce3+(aq)  

Identify the two half-reactions.

Oxidation half-reaction                          Reduction half-reaction

A) Fe 2+(aq) → Fe 3+(aq) + e−              Ce 4+(aq) + e  → Ce 3+(aq)

B) Ce 4+(aq) + e  → Ce 3+(aq)           Fe 2+(aq) → Fe 3+(aq) + e 

C) Fe 2+(aq) + e  → Fe 3+(aq)           Ce 4+(aq) → Ce 3+(aq) + e 

D) Ce 4+(aq) → Ce 3+(aq) + e            Fe 2+(aq) + e  → Fe 3+(aq)

E) Fe 3+(aq) →Fe 2+(aq) + e −              Ce 4+(aq) → Ce 3+ (aq) + e
