Loss Electrons → Oxidation

Gain Electrons → Reduction2


Reduction:     2 Fe3+(aq) →  2 Fe2+(aq)

Oxidation:      H2(g)  → 2 H+(aq)


Fe3+(aq) + e →  Fe2+                          E° = 0.771 V
2 H+(aq) + 2 e H2(g)                        E°= 0.00 V


To calculate for the standard cell potential, use the following equation:

E°cell=E°cathode-E°anode
