Question

Calculate the standard electrode potential for the redox reaction: Fe3+(aq) + e- → Fe2+(aq) Given that the standard electrode potential for the reduction of Fe3+(aq) to Fe2+(aq) is +0.771 V and the standard electrode potential for the reduction of H+(aq) to H2(g) is 0.000 V.

Answer 1

The standard electrode potential for the redox reaction Fe3+ aq  + e-  Fe2+ aq  is already given in the problem statement. It is +0.771 V. There is no need to involve the standard electrode potential for the reduction of H+ aq  to H2 g  in this case, as it is not part of the reaction being considered.
