Question

explain Reaction of acids with carbonates and metal hydrogen carbonates.(need observation)

Answer 1

All metal carbonates and hydrogen carbonates react with acids to form a corresponding salt, carbon dioxide and water.

Metal carbonate + Acid → Salt + Carbon dioxide + Water

Metal hydrogen carbonate + Acid → Salt + Carbon dioxide + Water

For example, sodium carbonate reacts with dilute hydrochloric acid as follows:

Na
