In alkaline medium, `H_(2)O_(2)` reacts with `Fe^(3+) and Mn^(2+)` separately to give:

Options

A. `Fe^(4+) and Mn^(4+)`
B. `Fe^(2+) and Mn^(2+)`
C. `Fe^(2+) and Mn^(4+)`
D. `Fe^(4+) and Mn^(2+)`

Answer

C

Explanation

`2K_(3)[overset(3+)(Fe)(CN)_(6)]+2KOH+2H_(2)O_(2)to2K_(4) [overset(2+)(Fe)(CN)_(6)]+2H_(2)O+O_(2)`
`overset(2+)(MnSO_(4))+H_(2)O_(2)tooverset(4+)(MnO_(2))+H_(2)SO_(4)`
