Hydrochloric acid & sodium carbonate react to produce sodium chloride, carbon dioxide and water. Brisk effervescence are seen due to carbon dioxide gas formation. read more
Sodium carbonate (Na2CO3) reacts with hydrochloric acid (HCl) to give sodium chloride (NaCl) and carbonic acid (H2CO3). The carbonic acid rapidly breaks down to give carbon dioxide and water, leaving the solution neutral. read more
