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].
A. At cathode Mn will be deposited initially
B. At cathode `H_(2)(g)` will be dposited initially
C. At cathode `Cl_(2)(g)` will be deposited initially
D. None of the above statements are correct
