Vedclass · Answer

(D) The oxidising capacity of a species is directly proportional to its standard reduction potential $(E^{\ominus})$.Higher the positive value of standard reduction potential,stronger is the oxidising agent.Comparing the given values:$Sn^{4+}/Sn^{2+} = +1.15 \ V$$Tl^{+}/Tl = +1.26 \ V$$Al^{3+}/Al = -1.66 \ V$$Pb^{4+}/Pb^{2+} = +1.67 \ V$Since $Pb^{4+}/Pb^{2+}$ has the highest positive reduction potential $(+1.67 \ V)$,it has the strongest oxidising capacity.

The standard reduction potential values of some of the $p-$block ions are given below. Predict the one with the strongest oxidising capacity.
