Explain why Cu^+ ion is not stable in aqueous solution ?

Assertion : Cuprous ion (Cu^(+)) has unpaired electrons while cupric ion (Cu^(++)) does not. Reason : Cuprous ion (Cu^(+)) is colourless where as cupric ion (Cu^(+2)) is blue in the aqueous solution.

Cu^(2+) ions give white precipitate with :
