What is the equation for the reaction between calcium carbonate and hydrochloric acid?

Answer 1

Calcium carbonate is NOT a metal, it is a compound that contains the ion of a metal.

The reaction is not, strictly speaking, neutralisation (since neutralisation reactions make a salt and water as the only products, and this reaction makes carbon dioxide as well) although the acid is neutralised!

The carbonate ions each accept two protons, forming H2CO3, most of which then breaks down to form CO2 and water.

The reaction is exothermic (but only just) so could be called " an exothermic reaction".

Answer 2

It is double displacement reaction of weak acid by strong acid.Since,neutralisation means formation of unionised molecule of water,according to Arrhenius'theory.In this reaction,carbonic acid is formed which loses carbon dioxide at room temperature.Here carbonic acid is displaced by hydrochloric acid.Hence,it is displacement reaction.Its equation is, CaCO3 + 2HCl -------> CaCl2 + H2CO3 but,H2CO3 loses CO2 at room temperature.Therefore it becomes, CaCO3 + 2HCl ------->Cacl2 + H2O + CO2

Answer 3

calcium is a base and hydrochloric acid is an acid. Acid with base gives salt and water. So calcium to hydrochloric acid will give calcium chloride(salt) and water which is called neutralization reaction

Answer 4

The equation for the reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl) is: CaCO3 + 2HCl -> CaCl2 + H2O + CO2. This reaction results in the formation of calcium chloride (CaCl2), water (H2O), and carbon dioxide (CO2).
