Answer» `FeSO_(3)` `MnO_(4)^(-)+8H^(+)+5e^(-)rarrMn^(2+)+4H_(2)O` no of electrons involved in the reqction =5 (a) oxidation of `FeSO_(3)`to `Fe_(2)(SO_(4))_(3)` `Fe^(2+)rarrFe^(3+)+e^(-)` `SO_(3)^(2-)+H_(2)OrarrSO_(4)^(2-)+2H^(+)+2E^(-)` (B) oxidation of `FeC_(2)O_(4)` `Fe^(2+)rarrFe^(3+)+e^(-)` `C_(2)O_(4)^(2-)rarr2CO_(2)+2e^(-)` (c ) oxidation of `Fe(NO_(2))_(2)` `Fe^(2+)rarrFe^(3+)` `2NO_(2)^(-)+2H_(2)Orarr2NO_(3)+4H^(+)+4e^(-)` (d) oxidation of `FeSO_(4)` `Fe^(2+)rarrFe^(3+)+e^(-)` no of ELECTRONIC involved =1since `FeSO_(4)` gives least number of electons therefore it will required least amount of L `MnO_(4)` for its oxidation |
