- Statement -I : \( \mathrm{Cu}^{2+} \) and \( \mathrm{Cd}^{2+} \) are separated from each other by first adding. \( \mathrm{KCN} \) solution and then passing \( \mathrm{H}_{2} \mathrm{~S} \) gas.
Because
- Statement -II : \( \mathrm{KCN} \) reduces \( \mathrm{Cu}^{2+} \) to \( \mathrm{Cu}^{+} \)and forms a complex with it.
