Answer:
You get a vigorous decomposition reaction where the carbonate radical dissociates, liberating carbon dioxide. ... Chemical reaction happens. Na2CO3 + 2HCl --> 2NaCl + CO2 + H2O. Since H2CO3 is a weak acid, HCl displaces CO3 2- to form H2CO3 which is very unstable and decomposes into CO2 has and water.
Hope it will help you.
