The colour showed by the solution of [Ti(H₂O)₆]³⁺ is:
Correct answer: D. Violet
- A. Blue and red
- B. Green
- C. Yellow
- D. Violet
Explanation
In [Ti(H₂O)₆]³⁺, the Ti atom has one valence electron which is excited when it absorbs yellow light. It appears violent due to the reflection of red and blue lights (complementary to yellow). So the compound appears violet.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
