WebReaction 3 was Cu(OH)2(s) + heat →CuO (s) + H2O (l) and was a bit different because Cu(OH)2(s) is known for being thermally unstable and in this specific reaction, heat was used instead of any other chemical to create a reaction. The balanced chemical formula of reaction 4 was CuO(s)+H2SO4(aq) →CuSO4(aq) + H2O (l) and was an acid-base reaction. Webevolution of bubbles ceases. The blue color should now be gone. A metallic precipitate of copper metal forms during this period. Vigorous evolution of hydrogen gas is also observed during the addition. After the reaction is complete, add 5 mL of 6M HCl solution and stir the mixture with a glass rod. This process removes any unreacted zinc metal.
