Question

what is the reaction when bariun carbonate is treated with sodium carbonate solution and the resultant mixture is treated with dilute hydrochloric acid

Answer 1

The reaction of hydrochloric acid(HCl) and sodium carbonate(NaCO3) yields a product of water (H20), carbon dioxide gas (CO2), and table salt (NaCl). The intermediate that is formed in situ is carbonic acid (H2CO3), but due to its unstable nature, it breaks down into water, carbon dioxide, and a salt.
