copper sulphate heated reaction

The formation of some cupric oxide ($\ce{CuO}$) would account for the appearance of an insoluble black precipitate. Sodium chloride,NaCl(s), (table salt) see CLEAPSS Hazcard HC047b. CuSO 4.5H 2 O is the chemical formula for copper sulphate crystals. Copper(II) sulfate is also used in the Biuret reagent to test for proteins. I tried reacting copper sulfate with sodium hydroxide to get copper hydroxide, which should precipitate, according to the following equation: $$\ce{2NaOH + CuSO4 -> Cu(OH)2(s) + Na2SO4}$$ I looked on Google Images, and the color of copper hydroxide is light-blue, but something interesting happened when I mixed these two solutions: the precipitate formed - and was originally light-blue, as .
