Question

what happens when metal carbonates and metal hydrogen carbonates react with acid write chemical equation for both​

Answer 1

Answer:

Acids react with carbonates and bicarbonate ( Hydrogen carbonate) liberating carbon dioxide gas with brisk effervence along with the formation of salt and water.

on passing the carbon dioxide gas evolved through lime water:

Ca(OH)2 + CO2 ------> CaCo3 + H2O

On passing excess carbon dioxide the following reaction takes place:

CaCO3 + H2O +CO2 ------> Ca(HCO3)
