Standard electrode potential data are useful for understanding the suitability of an oxidant in a redox titration. Some half cell reactions and their standard potentials are given below. MnO4 ' (aq.) + 8 H+ (aq.) + 5e' → Mn2+ →(aq.) + 4 H2O (l); E° = 1.51 VCr2O72' (aq.) + 14 H+ (aq.) + 6e' → 2 Cr3+ (aq.) + 7 H2O (l); E° = 1.38 V Fe3+ (aq.) e' → Fe2+ (aq.); E° = 0.77 V Cl2 (g) + 2e' → 2 Cl' (aq.); E° = 1.40 V Identify the only incorrect statement regarding the quantitative estimation of aqueous Fe(NO3)2.
