WebOlder students, already familiar with acid/base reactions, should be able to predict the identity of the compound formed, using the colour change as confirmation of that prediction. The symbol equation for the reaction is: CuO(s) + H 2 SO 4 (aq) → CuSO 4 (aq) + H 2 O(l) Otherwise, a simple word equation will be sufficient. WebMar 10, 2024 · The reaction of ethanol with surface OH groups on ZrO2, CuO/ZrO2, CuO, Al2O3, Ga2O3, NiO, and SiO2 was studied by IR spectroscopy. The basicity of oxides was followed by CO2 adsorption, and their ability to oxidize was investigated by H2-TPR. It has been found that ethanol reacts with surface OH groups forming ethoxy groups and water. …
