Web29 jan. 2012 · Expert Answer In an aqueous medium, Cu2+ is more stable than Cu+. This is because although energy is required to remove one electron from Cu+ to Cu2+, high hydration energy of Cu2+ compensates for it. Therefore, Cu+ion in an aqueous solution is unstable. It disproportionates to give Cu2+ and Cu. Answered by 30 Jan, 2012, 12:45: AM … WebThe blue solution on treatment with KI in weakly acidic medium, turns yellow and produces a white ppt. B.
