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))

Strong oxidising agent

=\mathrm{Co}^{+3}

No. of unpaired

\mathrm{e}^{-}

\mathrm{Co}^{+3}

\left[3 \mathrm{~d}^6\right]=4

Hence

\mu=\sqrt{\mathrm{n}(\mathrm{n}+2)}=\sqrt{24} \mathrm{BM}

Nearest integer
