Question

ti2+ is coloured ion whereas ti4+ is colourless​

Answer 1

Answer:

The ground state electronic configuration of Ti(22):[Ar]4s 2 3d 2

For Ti 2+ ion, the ground state electronic configuration is [Ar]3d 2

.

It contains two unpaired electrons. Thus d-d transition is possible.

For Ti 4+ ion, the ground state electronic configuration is [Ar]3d

0

.

All the electrons are paired. Hence, d-d transition is not possible and it is colourless.
