Question

What happens when dilute hydrochloric acid is added to sodium carbonate? Write a balanced chemical equation of the reaction involved.

Answer 1

When dilute hydrochloric acid reacts with sodium carbonate, then sodium chloride, carbon dioxide and water are formed.

\[\ce{\underset{Sodium carbonate}{Na2CO3_{(s)}} + \underset{Hydrochloric acid}{2HCl_{(aq)}} -> \underset{Sodium chloride}{2NaCl_{(aq)}} + \underset{dioxide}{\underset{Carbon}{CO2_{(g)}}} + \underset{Water}{H2O_{(l)}}}\]
