What happens when sodium carbonate reacts with dilute acid? (b) When dilute hydrochloric acid reacts with sodium hydrogen carbonate, Carbon dioxide gas is liberated. We recognize the presence of carbon dioxide by passing it through lime water which turns milky or a white precipitate of calcium carbonate is formed.

From the results of our studies, we conclude that even though hydrochloric acid and sodium bicarbonate react instantaneously, the resulting gas production is slow, mainly because CO2 produced from the dehydration of carbonic acid dissolves in water and is only slowly released into the gas phase.

Answer Verified 291.6k + views Hint: We know that a reaction where displacement of a less reactive metal from its compound occurs by a more reactive metal is termed as displacement reaction. The reactivity of metals is decided by the reactivity series of metals. Complete step-by step answer:
