Question

Which of the following equation depicts reducing nature of `H_(2)O_(2) `?
A. `2[Fe(CN)_(6)]^(4-) + 2H^(+) + H_(2)O_(2) to 2[Fe(CN)_(6)]^(3-) + 2H_(2)O`
B. `I_(2)+H_(2)O_(2) + 2OH^(-) to 2I^(-) + 2H_(2)O+O_(2)`
C. `Mn^(2+) + H_(2)O_(2) to Mn^(4+) + 2OH^(-)`
D. `PbS + 4H_(2)O_(2) to PbSO_(4) + 4H_(2)O`

Answer 1

Correct Answer - B
In reaction (b), `O_(2)` is evolved , therefore, it represents the reducing action of `H_(2)O_(2)`.
