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 oxidizing agent in aqueous solution is \( \_\_\_\_\_\_\_\_ \) \( \text{BM} \) (Near integer).
(Given atomic number : \( \mathrm{Ti: \, 22} \), \( \mathrm{V: \, 23} \), \( \mathrm{Cr: \, 24} \), \( \mathrm{Co: \, 27} \))
