Stability in aqueous conditions depends on the hydration energy of the ions when they bond to the water molecules . The Cu2+ ion has a greater charge density than the Cu+ ion and so forms much stronger bonds releasing more energy.The extra energy needed for the second ionisation of the copper is more than unsatisfactory for by the hydration, so much so that the Cu+ ion loses an electron to become Cu2+ which can then release this hydration energy. A nearby Cu+ ion is the most simple reduction target for the removed electron, which is why Cu(s) is also formed.Hence, Cu+ in is unstable in an aqueous solution..
