Explanation:
When ions are dissolved in water, they form aqueous solutions. Some ions have the same colour in aqueous solution, while others have different colours. The correct options for ions having the same colour in aqueous solution are B and D. Let's discuss each option in detail.
Option B: Ni2+ and Fe2+
- Ni2+ ions are green in colour in aqueous solution.
- Fe2+ ions are pale green or light yellow in colour in aqueous solution.
- When Ni2+ and Fe2+ ions are mixed, they give a green colour in aqueous solution.
- Therefore, Ni2+ and Fe2+ ions have the same colour in aqueous solution.
Option D: V4+ and Cr2+
- V4+ ions are blue in colour in aqueous solution.
- Cr2+ ions are also blue in colour in aqueous solution.
- When V4+ and Cr2+ ions are mixed, they give a blue colour in aqueous solution.
- Therefore, V4+ and Cr2+ ions have the same colour in aqueous solution.
Therefore, the correct options for ions having the same colour in aqueous solution are B and D.
