Predict which of the followingwill be coloured in aqueous solution? `Ti^(3+),V^(3+),Cu^(o+),Sc^(3+),Mn^(2+),Fe^(2+)` and `Co^(2+)` Give reasons for each.

Text Solution

Verified by Experts

`Ti^(3+),V^(3+),Mn^(2+),Fe^(3+)` and `Co^(2+)` are all coloured.
`MnO_4^(ɵ)` is also coloured but due to charge transfer. Only `Sc^(3+)` `(3d^0)` is colourless.
