Which of the following equation depicts reducing nature of H_2O_2 ?

Answer»

`2[Fe(CN)_6]^(4-) + 2H^(+) + H_2O_2 to 2[Fe(CN)_6]^(3-) + 2H_2O`
`I_2 + H_2O_2 + 2OH^(-) to 2I^(-) + 2H_2O + O_2`
`Mn^(2+) + H_2O_2 to Mn^(4+) + 2OH^(-)`
`Pbs+4H_2O_2 to PbSO_4 + 4H_2O`

Solution :`H_2O_2` ACTS as a oxidising agent and reducing agent in alkaline following REACTION indicate its reducing nature in basic medium.
`I_2 + H_2O_2+ 2OH^(-) to 2I^(-) + 2H_2O + O_2`
`2MnO_4^(-) + 3H_2O_2 to 2MnO_2 + 3O_2 + 2H_2O + 2OH^(-)`
