Question

Cu positive ion is not stable in aqueous solution why

Answer 1

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

Answer 2

Answer:the high hydration enthalpy of cu2+ in the aqueous solution compensates for the ionization energy IE 2
