Question

Write a balanced chemical equation for the preparation of each of following salts:
Copper carbonate

Answer 1

Hint: Copper is a chemical element with atomic number 29. It is a soft element but is tough in nature. It is easily mixed with other metals to form alloys such as bronze and many more. To solve this question, we need to know about the properties of copper and its tendency to form various compounds.

Complete step by step answer:
First of all, let’s discuss the basic properties of copper. Copper is a chemical element with atomic number 29. Its electronic configuration is $[Ar]3{d^{10}}4{s^1}$. It does not obey the Aufbau principle. Further, its melting point and boiling point are ${1084.62^ \circ }C$ and ${2562^ \circ }C$. Thus, it can be understood that it has a very high melting and boiling point. The symbol Cu denotes the Latin name of copper which is Cuprum. It can be classified as a native metal which can occur in nature in its pure form.
Now, copper carbonate is a grey color ionic solid compound that contains copper cations and carbonate anions. It is a non-flammable compound and can react immediately with water and air. Now, copper reacts with moist air having carbon dioxide gas to form basic carbonate. The reaction is as shown:
 $2Cu + {H_2}O + C{O_2} + {O_2} \to CuC{O_3}.Cu{(OH)_2}$
Further, this basic copper carbonate is heated in the presence of carbon dioxide gas. The reaction is as shown:
 $CuC{O_3}.Cu{(OH)_2} + C{O_2} \to 2CuC{O_3} + {H_2}O$

Note: Copper carbonate is used in some types of make-up products like lipstick. Although it can also be toxic to humans. Further, it also has been used for many years as an effective algaecide in farm ponds and in aquaculture operations.
