Which of the following species is reduced by `H_(2)O_(2)`A. `|Fe(CN)_(6)|^(4-)`B. `|Fe(CN)_(6)|^(3-)` in alkaline mediumC. `NO_(2)^(-)`D. `I^(-)//HCl`.

Answer» Correct Answer - B
`|Fe(CN)_(6)|^(3-)"is reduced to"|Fe(CN)_(6)|^(4-) "in alkaline solution".
2|Fe(CN)_(6)|^(3-)+2OH^(-)+H_(2)O_(2)to2|Fe(CN)_(6)|^(4-)+2H_(2)O+O_(2)`
