Question

The colour of $\left[Ti\right(H_{2}O{)}_6{]}^{+3}$ is due to _________

• A. Metal to Ligand Charge Transfer
• B. Ligand to metal Charge Transfer
• C. d-d
• D. None of the above

Answer 1

The correct option is C d-d

The colour of $\left[Ti\right(H_{2}O{)}_6{]}^{+3}$ is due to d-d transition. Any compound or ion showing colour is due to presence of unpaired electron. $\left[Ti\right(H_{2}O{)}_6{]}^{+3}$ has $d^1$ configuration and have one unpaired electron and because of this it shows d-d transition and has purple colour.
