Explain why `cu^(+)` ion is not stable in aqueous solutions?

(a) Why do transition metals and their compounds are found to be good catalysts? (b) The 5d series of transition metals have more frequent metal-metal bonding in their compounds than do the 3d and 4d metals. Explain. (c ) Why do transition metals form complexes? (d) Explain why Cu^+ ion is not stable in aqueous solution. (e ) Why is europium (II) more stable than cerium (II)?

Assertion : Cu^+ ion is not stable in aqueous solution. Reason : Cu^+ contains 3d-filled subshell.

Account for the following: (i) Cu^(+) ions are not stable in aqueous solution. (ii) Most of the transition metal ions exhibit paramagnetic behaviour.

Using the electrochemical series table, explain why Cu (I) sulphate does not exist in aqueous solution

Out of Cu^(2+) and Cu^(+) , which ion is unstable in aqueous solution and why?

Cu^(+) ion is not stable in aqueous solution because of disproportionation reaction. E^(@) value disproportionation of Cu^(+) is (given E_(cu^(2+)//cu)^(@)=0.34 V)
