Q23. What happens when a copper vessel is exposed to moist for long time? Write word equation of the reaction |
|
Answer» ong>Answer: Copper is comparatively less reactive but reacts with REAGENTS like OXYGEN and WATER in atmosphere in a slow time. Also carbon dioxide helps in the reaction. As it is a metal, it will START corroding.. After some days, we will observe GREENISH layer on the surface of copper vessel due to the formation of copper carbonate. The required reaction is: Copper when reacts with carbon dioxide, water and oxygen forms basic copper carbonate. The basic carbonate is a green coloured substance formed due time. Another example is the statue of liberty in New York, USA. |
