Which oxide reacts with hydrochloric acid? 1) Na2O 2) CO2 3) Co 4) SO3

In this task you will need to determine with which of the oxides hydrochloric acid reacts.

1) Na2O.

This compound is called sodium oxide. sodium oxide reacts with acids, therefore reacts with hydrochloric acid.

Na2O + HCl = NaCl + H2O.

when sodium oxide interacts with hydrochloric acid, as a result, sodium chloride and water compounds are formed.

2) CO2.

This compound is called carbon monoxide. Carbon monoxide is an acidic oxide, therefore it does not react with acids.

3) CO.

This compound is called bivalent carbon monoxide. To carbon monoxide with acidic oxide, so it does not react with hydrochloric acid.

4) SO3.

This compound is called sulfur oxide. This compound is an acidic oxide, therefore it does not react with hydrochloric acid.
