Vedclass · Answer

(C) The electronic configuration of $Ti^{3+}$ is $[Ar] 3d^1$. Since $Ti^{3+}$ contains one unpaired electron in the $d$-orbital,it undergoes $d-d$ transition and appears colored in an aqueous solution. In contrast,$Sc^{3+}$ $(3d^0)$,$La^{3+}$ $(4f^0)$,and $Lu^{3+}$ $(4f^{14})$ do not have unpaired electrons,making them colorless.

Which of the following ions will be colored in an aqueous solution?
