Basic oxides of divalent copper. This is the highest copper oxide.
Copper 2 oxide takes the form of black crystals, which are almost insoluble in water. Is reacted with the acid and the reaction forms the corresponding salt of bivalent copper, as well as water. With its fusion with alkali reaction products presented cuprates. The decomposition of the copper (II) oxide occurs at a temperature of about 1100 o C. Ammonia, carbon monoxide, hydrogen and carbon can be removed from this compound to metallic copper.
With this oxide dyed green or blue enamel and glass, as well as produce a variety of copper-ruby last. In the laboratory, this oxide exhibit reducing properties of substances.
