Question

Among the following which is the strongest oxidizing agent?

• A. $Mn^{3+}$
• B. $Fe^{3+}$
• C. $Ti^{3+}$
• D. $Cr^{3+}$

Answer 1

Answer: (A)

$Mn^{3+}$

Answer 2

$E^∘_{Fe^{3+}|Fe^{2+}} = +0.77\ V$
$E^{∘}_{Ti^{3+}|Ti^{2+}} = −0.37\ V$
$E^∘_{Mn^{3+}|Mn^{2+}} = +1.57\ V$
$E^∘_{Cr^{3+}|Cr^{2+}} = −0.41\ V$
$Mn^{+3}$ is the best oxidising agent among the given series.

So, the correct option is (A): $Mn^{+3}$
