Explain why Cu+ ion is not stable in aqueous solutions?

Asked by prernamehta | 29th Jan, 2012, 07:09: 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.
