The spin-only magnetic moment value of the ion among $\mathrm{Ti}^{2+}, \mathrm{V}^{2+}, \mathrm{Co}^{3+}$ and $\mathrm{Cr}^{2+}$, that acts as strong oxidising agent in aqueous solution is _________ BM (Near integer).
(Given atomic numbers : $\mathrm{Ti}: 22, \mathrm{~V}: 23, \mathrm{Cr}: 24, \mathrm{Co}: 27$)
Answer (integer)
5
Solution
<p>The ion which acts as strong oxidising agent in aqueous solution is $\mathrm{Cr}^{2+}:[\mathrm{Ar}] 4 s^{\circ} 3 d^4$</p>
<p>$\mu=\sqrt{4(4+2)}=4.89 \Rightarrow 5$</p>
