Standard electrode potential data are useful for understanding the suitability of an oxidant in a redox titration. Some half cell reaction and their standard potentials are given below: MnO_(4)^(-)(aq) +8H^(+)(aq) +5e^(-) rarr Mn^(2+)(aq) +4H_(2)O(l) E^(@) = 1.51V Cr_(2)O_(7)^(2-)(aq) +14H^(+) (aq) +6e^(-) rarr 2Cr^(3+)(aq) +7H_(2)O(l), E^(@) = 1.38V Fe^(3+) (aq) +e^(-) rarr Fe^(2+) (aq), E^(@) = 0.77V CI_(2)(g) +2e^(-) rarr 2CI^(-)(aq), E^(@) = 1.40V Identify the only incorrect statement regarding quantitative estimation of aqueous Fe(NO_(3))_(2)

Consult the table of standard electrode potential and suggest three substances that can oxidize Fe^(2+) ions under suitable conditions.

Electrode potential data are used for predicting fessibility of any process. These are particularly useful in deciding products obtained on electrolysis and also on suitability of any substance for quantitative estimation. Some of the electrode potentials are given below: An aqueous solution is taken comprising of Fe^(+3),Mn^(+2),Fe^(+2),C_(2)O_(4)^(2-) and Cl^(-) all at standard conditions. The solution is subjected to electrolysis using inert electrodes ensuring that pH of the solution remains as 7. Identify the option which is correct regarding products obtained [assume that except [H^(+)] all other species involved are present at standard conditions].
