Question

How do metal carbonates and metal hydrogen carbonates react with acids

Answer 1

metal carbonates reacts with acids to form carbon dioxide, water and metal combined with negative part of acid.
example
Na2CO3 + 2HCl → 2NaCl + H2O + CO2
( H2CO3 → H2O + CO2)
metal hydrogen carbonate:
NaHCO3 + HCl → NaCl + H2O + CO2

Answer 2

Answer:

Metal carbonates and Metal Hydrogencarbonates reacts with acids and produces corresponding metal salt, carbon dioxide and water. ... Both the reaction produces CO2 which on passing through lime water makes lime water milky due to formation of calcium carbonate. On passing excess carbon dioxide following reaction occurs
