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: On adding `KMnO_(4)` solution to an aqueous solution of ferrous oxalate in presence of `HCl`, it is observed that 0.1 "mole" of `Cl_(2)(g)` and 0.2 "mole"s of `CO_(2)(g)` was obtained. What must be the amount of `KMnO_(4)` compound taken?A. 0.1"mole"sB. `(0.4)/(5)` "mole"sC. `(0.3)/(5)` "mole"sD. 0.5 "mole"s
