Molecular formula:Cu₂(OH)₂CO₃
Molecular weight:221.076
Physical and chemical properties:it’s a peacock green color,so it’s also called malachite.it’s a precious mineral gem.It is produced by the reaction of copper with substances such as oxygen,carbon dioxide and water vapor in the air,also known as copper green and green.Heating in the air eill break down into copper oxide,water and carbon dioxide.soluble in acids and produce corresponding copper salts.in nature in the form of malachite.
Applications and Usages: Used in catalysts,pyrotechnics,pesticides,pigments,feedstuffs,fungicides,electroplating，anticorrosion and the manufacture of copper compounds as analytical reagents for the preparation of other copper compounds salt,solid phosphor activator.
