Question
When acid reacts with metal carbonate, _______ is/are
formed.Solution
When an acid reacts with a metal carbonate, salt, water, and carbon dioxide are produced. • Example: Hydrochloric acid on reaction with sodium carbonate forms sodium chloride, carbon dioxide and water. 2HCl+Na2CO3 → 2NaCl+CO2+H2O  Sulfuric acid + Ferrous carbonate → Ferrous sulfate + water + carbon dioxide ■H2SO4 + FeCO3 --> FeSO4 + H2O + CO2 • The salt that forms will depend on the specific acid and metal carbonate which were used in the reaction.
