When Caustic soda solution is added to Cu(NO3)2 solution, the following reaction takes place:
Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(S) + 2NaNO3(aq)
When we heat it further, the greenish blue copper hydroxide decomposes to form slightly black ppt. of copper oxide.
\[\ce{Cu(OH)2(S) ->[\Delta] CuO(s) + H2O(g)}\]
