The chemical equation for the decomposition of basic copper carbonate by heating is Cu2 (OH) 2co3 = △ = = 2cuo+H2O+CO2 =

Basic copper carbonate is malachite green, so it is also called malachite, which is a precious mineral gem. It is a substance produced by the reaction of copper with oxygen, carbon dioxide and water vapor in the air, also known as verdigris, with a green color. Heating in air will decompose into copper oxide, water and carbon dioxide.

Extended information

Basic copper carbonate can be used in organic catalysts, fireworks manufacturing and pigments. In agriculture, it is used as a preventive, insecticide and antidote to phosphorus toxicity, and also as a fungicide for seeds; Mixing with asphalt can prevent livestock and wild rats from gnawing saplings; Used as an additive for copper in feed, as a dealkalizing agent in crude oil storage and as a raw material for producing copper compounds. It can also be used for electroplating, anticorrosion and analytical reagents.

during transportation, it shall be operated in a closed manner and locally exhausted. Prevent dust from being released into the air of the workshop.
