Answer» Solution :Assign REASON for the FOLLOWING: Copper (I) ION is not known in aqueous solutions. `2Cu^(+) rarr Cu^(2+) + 2 Cu` The greater stability of `Cu^(2+)` ion as compared to `Cu^+` is due to the much more negative `Delta_(hydH)` of`Cu^(2+)`than `Cu_((aq))^(+)`which mor than compensates for the second IONIZATION enthalpy of Cu. |
