Question

What happens when sodium carbonate reacts with hydrochloric acid?

Answer 1

Answer:

Explanation:

Well, HCl is an acid and it reacts with the metal carbonate Na2CO3 to give CO2 (carbon dioxide) , H2O and NaCl ( sodium chloride).  

As, it involves the release of carbon dioxide a brisk effervescence is seen.

The reaction follows:

Na2CO3 + HCl ---> NaCl + CO2 + H2O

Generally, acids react with metal carbonates to give out water, metal salt, and carbon dioxide.
