In which of the following reaction `H_(2)O_(2)` acts as a reducing agent -
(I) `H_(2) O_(2) + 2H^(+) + 2e^(-) to 2H_(2) O`
(II) `H_(2)O_(2) - 2e^(-) to O_(2) + 2H^(+)`
(III) `H_(2)O_(2) + 2e^(-) to O_(2) + 2H^(+)`
(IV) `H_(2)O_(2) + 2OH^(-) to 2H_2O + O_2 + 2e^-`

Options

A. (II),(IV)
B. (I),(II)
C. (III) , (IV)
D. (I),(III)

Answer

A

Explanation

In both II and IV, `H_(2)O_(2)` is oxidised to `O_(2)`. Hence it acts as a reducing agent.
