Question

what is the reaction between acid and a metal carbonate or metal hydrogen carbonate ​

Answer 1

• Metal Hydrogen carbonates are formed by reaction of metal salt with HCO3 or with a hydrogen carbonates of a more reactive metal. Metal carbonates and Metal Hydrogencarbonates reacts with acids and produces corresponding metal salt, carbon dioxide and water.

Answer 2

Explanation:

When an Acid reacts with a carbonate and or bicarbonate, caborn dioxide (CO2) is liberated and when it reacts with a metal (active metal) Hydrogen gas (H2) is liberated.

HCl + Na2CO3 → NaCl + CO2(g)+ H2O

HCl + Na → NaCl + H2(g)
