`Sc^(3+)` is colourless is aqueous solution whereas `Ti^(3+)` is coloured. |
|
Answer» Electronic configuration of `._(21)Sc^(3+)` is [Ar `3d^(0)` and `._(22)Ti^(3+)` is [Ar] `3d^(1)`. Therefore due to absence of unpaired electron `Sc^(3+)` is colourless and due to presence of one unpaired electron d-d transtion takes place hence `Ti^(3+)` is coloured. |
