Answer variants:
Sodium bicarbonate (\(NaHCO_3\)) functions as an antacid, neutralising excess hydrochloric acid (\(HCl\)) in our stomach.
Sodium carbonate \(Na_2CO_3\) reacts with hydrochloric acid, carbon dioxide gas \(CO_2\) is liberated.
Because hydrogen gas is heavier than air, it cannot be collected by the downward displacement of air.
 
1. Which gas is liberated when sodium carbonate reacts with hydrochloric acid?
 
2. What is the utility of the reaction between \(NaHCO_3\) and \(HCl\) in daily life situation?
