Question

Cu+ ion is unstable in an aqueous solution.
a)Due to unpaired electron b)Due to paired electron c)Due to disproporsanation of Cu+ ions d)All of the above ​

Answer 1

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.
