  • Copper(I) Oxide Structure, Properties and Uses of Cu2O

    What is Copper(I) Oxide? Copper(I) Oxide is also called as cuprous oxide an inorganic compound with the chemical formula Cu 2 O. It is covalent in nature. Copper(I) oxide crystallizes in a cubic structure. It is easily reduced by hydrogen when heated It undergoes disproportionation in acid solutions producing copper(II) ions and copper.
