In alkaline medium, `H_2O_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^(3+) and Mn^(4+)`
D. ` Fe^(4+) and Mn^(2+)`

Answer

C

Explanation

`2Fe^(2+) + 4 OH^(-) + H_2 O_2 to 2 Fe^(3+) (OH)_3`
` Mn^(2+) + H_2 O_2 + 2OH^(-) to overset(+4)(MnO_2) + 2H_2 O`
