why Cu+ unstable in aquous state but Cu2+ is stable?

Asked by kanwal sandhu | 21st Jan, 2012, 08:12: PM

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.
