Explain why Cu^+ ion is not stable in aqueous solution? |
| Answer» Solution :In aqueous medium `Cu^(2+)` is more STABLE than `Cu^+`. This is because of much HIGHER HYDRATION enthalpy of `Cu^(2+)` compared to `Cu^+`. Therefore `Cu^+` compounds-are unstable in aqueous solution and undergoes DISPROPORTIONATION as shown below: `2Cu^+(AQ)toCu^(2+)+(aq)+Cu(s)` | |
