Question

Which among the following cations produces colourless aqueous solution in their respective oxidation state?

• A. $Ti^{3+}$
• B. $V^{3+}$
• C. $Sc^{3+}$
• D. $Cu^{2+}$

Hint:

Chemistry Tip: Always check for $d^0$ (like $Sc^{3+}, Ti^{4+}$) or $d^{10}$ (like $Zn^{2+}, Cu^+$) configurations when asked to identify colourless or diamagnetic transition metal ions.
