1.	Standard potential (E^(@)) for some half reactions are given below (i) Sn^(4+) + 2e^(-) to Sn^(2+) , E^(@) = 0.15 V (ii) 2Hg^(2+) + 2e^(-) to Hg_(2)^(2+), E^(@) = 0.92 V (iii) PbO_(2) + 4H^(+) +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 stronger oxidising agent than `Pb^(4+)` `Sn^(2+)` is a stronger reducing agent than `Hg_(2)^(2+)` `Pb^(2+)` is a stronger oxidizingagent than `Pb^(4+)` `Pb^(2+)` is a stronger reducing agent than `Sn^(2+)` Solution :Electrochemical SERIES, more the reduction potential, stronger the oxidizing POWER and VICE VERSA
