48.

[Ti(H2O)6]3 is coloured while [Sc(H2O)6]3 is colourless. Explain.

Answer»

Ti [Ti(H₂O)₆]³ is in +3 oxidation state and

Sc in [Sc(H₂O)₆]³ is in +3 oxidation state.

The outer electronic configuration of Sc, Ti and the corresponding trivalent ions are

Sc₂₁ : 3d¹ 4s² Sc³⁺ : 3d⁰

Ti₂₂ : 3d¹ 4s² Ti³⁺ : 3d¹

Since there is no electron in 3d orbitals of Sc d-d transition is not possible hence [Sc(H₂O)₆]³⁺ is colourless. But Ti³⁺ in [Ti(H₂O)₆]³⁺ has one electron in 3d orbitals hence d-d transition is possible hence it is coloured.
