Which of the following equations depict the oxidising nature of H_(2)O_(2) ?

Answer»

`2MnO_(4)^(-) + 6H^(+) + 5H_(2)O_(2) to 2Mn^(2+) + 8H_(2)O+ 5O_(2)`
`2Fe^(3+) + H_(2)O_(2) to 2Fe^(2+) + 2H^(+) + O_(2)`
`2I^(-) + 2H^(+) + H_(2)O_(2) to I_(2) + 2H_(2)O`
`KIO_(4)+ H_(2)O_(2) to KIO_(3) + H_(2)O+O_(2)`

Solution :Only in REACTION (c) , `O_(2)` is evolved , therefore, it REPRESENTS the reducing action of `H_(2)O_(2)`.
