MCQ
Given:
$C{o^{3 + }}{e^ - } \longrightarrow C{o^{2 + }};\,{E^o} = 1.81\,V$
$P{b^4} + 2{e^ - } \longrightarrow P{b^{2 + }};\,{E^o} = + 1.67\,V$
$C{e^{4 + }} + {e^ - } \longrightarrow C{e^{3 + }};\,{E^o} = + 1.61\,V$
$B{i^{3 + }} + 3{e^ - } \longrightarrow Bi;\,{E^o} = + 0.20\,V$
Oxidizing power of the species will increase in the order
- A$C{e^{4 + }} < P{b^{4 + }} < B{i^{3 + }} < C{o^{3 + }}$
- B$C{o^{3 + }} < P{b^{4 + }} < C{e^{4 + }} < B{i^{3 + }}$
- ✓$B{i^{3 + }} < C{e^{4 + }} < P{b^{4 + }} < C{o^{3 + }}$
- D$C{o^{3 + }} < C{e^{4 + }} < B{i^{3 + }} < P{b^{4 + }}$
