Answer;

CaCO3(s)+ 2 H+(aq)  → Ca+2 + CO2(g) + H2O(l)

Explanation;

  • The reaction of an acid with calcium carbonate is an example of an acid-base reaction.
  • In these reactions, an acid will react with a base to form a salt and water. The acid was neutralized by the base.
  • For example, CaCo3 will neutralize HCl by the following equation:

2HCl(aq) +CaCO3(s) → CaCl2(aq) + H2O(l) + CO2(g)

The reaction between calcium carbonate and a hypothetical acid is shown by; CaCO3(s) + 2HA(aq) -----> CaA2(aq) + CO2(g) + H2O(l).

Calcium carbonate is a basic substance. A base is a substance that reacts with an acid to yield salt and water only. A base may or may not be soluble in water.

The reaction of the base calcium carbonate with a hypothetical acid HA occurs as follows; CaCO3(s) + 2HA(aq) -----> CaA2(aq) + CO2(g) + H2O(l). Hence, a salt, water and carbon dioxide are produced.
