Which of the following metal ions is colourless?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The ions Ti3+, V4+, Cr4+ are paramagnetic therefore, exhibit colours due to d-d transitions. The Sc3+ ion is diamagnetic with electronic configuration of argon and does not exhibit colour.
