Explanation:


When sodium carbonate is added to dilute hydrochloric acid, gas bubbles are observed. This is because carbon dioxide (CO2) is given off in the reaction. The reaction between the two chemicals can be represented as follows:


Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l)


Assertion (A) : Gas bubbles are observed when sodium carbonate is added to dilute hydrochloride acid.


This assertion is true because gas bubbles are indeed observed when sodium carbonate is added to dilute hydrochloric acid.


Reason (R) : Carbon dioxide is given off in the reaction.


This reason is also true because carbon dioxide is one of the products formed in the reaction between sodium carbonate and dilute hydrochloric acid.


Explanation of Reason (R) :


When sodium carbonate is added to dilute hydrochloric acid, a chemical reaction takes place. In this reaction, sodium carbonate reacts with hydrochloric acid to form sodium chloride, carbon dioxide, and water. Carbon dioxide gas is given off as a product of this reaction, which is responsible for the gas bubbles observed when sodium carbonate is added to dilute hydrochloric acid.


Therefore, both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A). Hence, option (A) is the correct answer.
