The green coating on the surface of the copper vessel is a mixture of the copper carbonate and the copper hydroxide.
• Copper is a highly reactive metal which reacts which the atmospheric elements if we keep a copper object without any kind of external covering.
• The copper reacts with the atmospheric oxygen and water vapour in order to produce copper oxide and copper carbonate.
• This produced copper oxide and copper carbonate forms a mixture on the external surface of the copper metal and the surface appears green.
