Vedclass · Answer

(C) The color of transition metal ions in aqueous solution is due to $d-d$ transitions. $Co^{2+}$ ions in aqueous solution exist as $[Co(H_2O)_6]^{2+}$,which is pink in color. $Mn^{2+}$ ions in aqueous solution exist as $[Mn(H_2O)_6]^{2+}$,which is also pink in color. Therefore,both $Co^{2+}$ and $Mn^{2+}$ exhibit a pink color.
