Determination of the Empirical Formula of Copper OxideExperiment OverviewThis experiment is designed to determine the empirical formula of copper oxide. Since copper has two common oxidation states, +1 and +2, there are two possible forms of copper oxide: copper(I) oxide, Cu2O, and copper(II) oxide, CuO. Copper oxide is insoluble in water but dissolves in acid. A weighed sample will be dissolved in acid, and an excess of zinc metal will be added to the solution to cause metallic copper to be formed. Excess zinc can be removed by physical means (fish out the pieces) or chemical means (dis
