Chemistry - Redox Reactions Question with Solution | TestHub

Atom in highest oxidation state can oxidize iodide to liberate${\mathrm{I}}_2$which is volumetrically measured by iodometric titration using hypo solution.
$2{\mathrm{I}}^{-}\to {\mathrm{I}}_2$
$\mathrm{P}{\mathrm{b}}^{+2}\to$Lowest oxidation state can not oxidise iodide to${\mathrm{I}}_2$.
