Cu^+ ion is not stable in aqueous soluti...

`Cu^+` ion is not stable in aqueous solution because of diproportionation reaction . `E^(@) ` value for the disproportionation of `Cu^(+)` is :
`(E_(cu^(2+)// cu^+)^(@) = + 0.15 V , E_(cu^(+) // cu)^(@)= + 0.34 V )`

A

`Cu_((aq))^(+2)` is more stable than `Cu_((aq))^(+)`

B

`Cur_((aq))^(+2)` can form interstitial compounds in aqueous solution

C

The equilibrium constant for `Cu_((aq))^(+) hArr Cu_((aq))^(+2) + Cu` is very high

D

The equilibrium constant for `Cu_((aq))^(+2) hArr Cu_((aq))^(+2) = Cu` is very low

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`Cu^(+2)` is more stable is aqueous medium due to hydration energy
