Consider the following reaction
Fe+3 + e- = Fe+2
E
O = 0.771
When the potential of a platinum electrode .immersed in a solution that is 10-4 M in iron (III) ion iron (II)
ion and perchloric acid is measured against a standard hydrogen electrode a reading of close to 0.77V is
obtained as predicted by theory, if perchloric acid is added to this mixture until the acid concentration is
0.1M, however the potential is found to decreased to about 0.75V.Explain it?
