Write down disproportionation reaction of Cu^+ ion

The reduction potential diagram (Latimer diagram) for Cu is acid solution Calculate x. Does Cu^(+) disproportionate in the solution?

(a) Why are Zn^(2+) salts white while Cu^(2+) salts are blue ? (b) What is meant by 'disproportionation' ? Write the disproportionation reaction of Cu^+ in aqueous solution.

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 )

The reduction potential diagram for Cu in acid solution is : Calculate X . Does Cu^(+) disproportionate in solution ?

The reduction potential diagram for Cu in acid solution is : Calculate X . Does Cu^(+) disproportionate in solution ?

Statement-1: Many copper (I) compound are unstable in aqueous solution and undergo disproportionation. Statement-2: Cu^(2+) I mre stable than Cu^(+) because of much more negative Delta_(hyd)H^(@) of Cu^(2+) than Cu^(+) , which more than compensates for seconds ionisation enthalpy.
