In which of the following paris both the ions are coloured in aqueous solution? (Atomic number, `Sc - 21, Ti = 22, Ni = 28, Cu = 29, Co = 27)`

A

`Ni^(2+)` and `Cu^(+)`

B

`Sc^(3+)` and `Ti^(3+)`

C

`Sc^(3+)` and `Co^(2+)`

D

`Ni^(2+)` and `Ti^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Ni^(2+)` and `Ti^(3+)` ions coloured in aqueous solution because they contain unpaired electrons.
