In the reaction HAsO_(2)+Sn^(2+) rarr As+Sn^(4+)+H_(2)O oxidising agent is

Answer»

`Sn^(2+)`
`Sn^(4+)`
`As`
`HAsO_(2)`

Solution :Oxidizing agent itself, undergoes REDUCTION during a redox REACTION
`OVERSET(+3)(HAsO_(2))+overset(+2)(Sn) rarr overset(0)(As)+overset(+4)(Sn)+H_(2)O`
Hence, here `HAsO_(2)` is acting as oxidizing agent.
