Question

What happens when $C{{O}_{2}}$ reacts with the following compounds?

Answer 1

The given substance in the question is Sodium (Na) and it is a metal, when it is treated with carbon dioxide, then there will be the formation of a salt in which cation will be sodium and anion will be carbonate.

Complete answer:
Metals are those elements that are present on the left side of the periodic table. Mostly the metals belong to group 1 (alkali metals) and group 2 (alkaline earth metals). There are many properties of metals like electropositive nature, malleable, ductile, heat conductivity, electricity conductivity; their oxides are basic, etc.
The given compound or substance in the question is a metal. Na means sodium which is an element of group 1 (alkali metals) and it is basic in nature.
Now, this sodium metal is treated with carbon dioxide. As carbon dioxide is acidic in nature when it is treated with sodium there will be the formation of a salt. In this salt, the cation will be sodium ion and the anion will be carbonate ion. Therefore, the salt formed is sodium carbonate. There is a by-product also in this reaction, i.e., carbon formed in very less amount. The balanced reaction of sodium with carbon dioxide is given below:
$4Na+3C{{O}_{2}}\to 2N{{a}_{2}}C{{O}_{3}}+C$
We can also call sodium carbonate, sodium carbonate, or carbonic acid disodium salt.

Note:
When carbon dioxide reacts with the hydroxide form of alkaline earth metal elements, then also the main product formed is metal carbonate. In some cases when the metal reacts with carbon dioxide then it gets metal oxide.
