Question

Explain why cu ion is not known in aqueous solution

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+ionin an aqueous solution is unstable.

Answer 2

Hello,

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.
