Copper (II) oxide (copper oxide) CuO - bivalent copper oxide . Black crystals, under normal conditions, are quite stable, practically insoluble in water. It is found in nature in the form of the mineral tenorite ( melaconite ) of black color.

The crystal lattice of copper oxide is characterized by the following parameters: monoclinic syngony , space group C _2h , cell parameters a = 0.46837 (5) nm , b = 0.34226 (5) nm , c = 0.51288 (6) nm , α = 90 ° , β = 99 , 54 (1) ° , γ = 90 ° . The copper atom is surrounded by four oxygen atoms and has a distorted flat configuration.

Content

Getting

You can get copper (II) oxide:

heating metal copper in air (at temperatures below 1100 ° C):

{\mathsf {2Cu+O_{2}\rightarrow 2CuO}}

{\ displaystyle {\ mathsf {2Cu + O_ {2} \ rightarrow 2CuO}}}

heating copper (II) hydroxide , its nitrate or carbonate :

{\mathsf {2Cu(NO_{3})_{2}\rightarrow 2CuO+4NO_{2}+O_{2}}}

{\ displaystyle {\ mathsf {2Cu (NO_ {3}) _ {2} \ rightarrow 2CuO + 4NO_ {2} + O_ {2}}}}

{\mathsf {CuCO_{3}\rightarrow CuO+CO_{2}}}

{\ displaystyle {\ mathsf {CuCO_ {3} \ rightarrow CuO + CO_ {2}}}}

{\mathsf {Cu(OH)_{2}\rightarrow CuO+H_{2}O}}
