Standard potentials (E°) for some half-reactions are given below: Sn^(4+) + 2e rightarrow Sn^(2+) , E^(@) = + 0.15V 2Hg^(2+) + 2e rightarrow Hg_(2)^(2+) , E^(@) = 0.92 V pbo_(2) + 4H^(+) + 2e rightarrow pb^(2+)+ 2H_(2)O , E^(@) = + 1.45 V Based on the above , Which one of the following statement is correct?

Answer»

`SN^(4+)` is a STRONGER OXIDISING AGENT than `Pb^(4+)`.
`Sn^(2+)` is a stronger reducing agnet than `Hg_(2)^(2+)`.
`Hg^(2+)` is a stronger oxidising agent than `Pb^(4+)`.
`Pb^(2+)` is a stronger reducing agnet than `Sn^(2+)`.
