Standard potentials (E^(@)) for some half-reactions are given below : Sn^(4+) + 2e to Sn^(2+) , E^(@) = +0.15 V 2 Hg^(2+) + 2e to Hg_(2)^(2+) , E^(@) = 0.92 V PbO_(2) + 4 H^(+) + 2e to Pb^(2+) + 2H_(2)O , E^(@) = +1.45 V Based on the above , which one of the following statements is correct ?

Answer»

`Sn^(4+)` is a strongest OXIDISING agent than `Pb^(4+)`
`Sn^(2+)` is a strongest reducing agent than `Hg_(2)^(2+)`
`Pb^(2+)` is a strongest oxidising agent than `Pb^(4+)`
`Pb^(2+)` is a strongest reducing agent than `Sn^(2+)`

Solution :GREATER the REDUCTION potential , stronger is the oxidizing agent or WEAKER is the reduction agent .
