Ionisation Enthalpy & Oxidation StatesD & F Block

Why is Cu2+(aq)Cu^{2+}(aq) more stable thanCu+(aq) Cu^+(aq)despiteCu+ Cu^+having a stable3d10 3d^{10}configuration?

Expert Answer

The high negative Hydration Enthalpy of Cu2+Cu^{2+} compensates for the energy required to remove the second electron (2nd IE).
