Vedclass · Answer

(A) The ion that acts as a strong oxidizing agent in aqueous solution is $Co^{3+}$ because it has a high reduction potential $(Co^{3+} + e^{-} \rightarrow Co^{2+})$.The electronic configuration of $Co^{3+}$ $(Z = 27)$ is $[Ar] 3d^6$.The number of unpaired electrons $(n)$ in $3d^6$ is $4$.The spin-only magnetic moment is calculated as $\mu = \sqrt{n(n+2)} \ BM$.$\mu = \sqrt{4(4+2)} = \sqrt{24} \ BM \approx 4.9 \ BM$.The nearest integer value is $5$.

The spin-only magnetic moment value of the ion among $Ti^{2+}$,$V^{2+}$,$Co^{3+}$,and $Cr^{2+}$ that acts as a strong oxidizing agent in aqueous solution is .......... $BM$ (nearest integer).
(Given atomic numbers: $Ti = 22, V = 23, Cr = 24, Co = 27$)
