WebThe Empirical Formula of a Copper Oxide Reading assignment: Chang, Chemistry 10th edition, pp. 55-58. Goals The reaction of hydrogen gas with a copper oxide compound will … WebThe hydrogen peroxide oxidizes the copper metal to form copper ions (Cu²⁺) and water (H₂O). This reaction causes the copper to lose its bright, shiny appearance and turn into a dull brownish-red color. As the copper oxidizes, it also reacts with the hydrogen peroxide to produce copper oxide (CuO) and oxygen gas (O₂).
