The aqueous solution containing which one of the following ions will b...
Sc3+ ion will form a colourless solution.
- Explanation:
- Scandium (Sc) has an atomic number of 21.
- Scandium ions in the +3 oxidation state (Sc3+) do not have any partially filled d orbitals.
- Since Scandium does not have any unpaired electrons in its d orbitals, it does not exhibit any d-d transitions that lead to the absorption of visible light.
- As a result, the aqueous solution containing Sc3+ ions will be colourless.
- On the other hand, Fe2+, Ti3+, and Mn2+ ions have partially filled d orbitals, and they can exhibit d-d transitions that result in the absorption of certain wavelengths of light, giving coloured solutions.
- Therefore, the correct answer is option 'A' - Sc3+ ion will form a colourless solution.
