Given:
$C o^{3 +} + e^{-} \to C o^{2 +}; E ° = + 1.81 V$
${P b}^{3 +} + {2 e}^{-} \to {P b}^{2 +}; E ° = + 1.67 V$
$C e^{4 +} + e^{-} \to C e^{3 +}; E ° = + 1.61 V$
${B i}^{3 +} + {3 e}^{-} \to B i; E ° = + 0.20 V$
Oxidizing power of the species will increase in the order:

Options:

Answer:

Solution:

Higher the value of $E_{Red}^{0};$ higher will be its oxidizing power.

Hence correct order is $B i^{+ 3} < C e^{+ 4} < P b^{+ 4} < C o^{+ 3}$
