The equation CaCO3 + 2HCl -> CaCl2 + H2O + CO2

  1. Detailed information about the equation CaCO3 + 2HCl -> CaCl2 + H2O + CO2
    The above equation describes the reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl), resulting in the formation of calcium chloride (CaCl2), water (H2O), and carbon dioxide gas (CO2).

  2. Reaction Conditions
    This reaction takes place at room temperature and does not require light.

  3. Reaction Process
    Calcium carbonate, when it comes into contact with hydrochloric acid, is decomposed by this acid to produce calcium chloride, water, and carbon dioxide gas. This reaction will occur until one of the reactants is exhausted.

  4. Phenomenon occurs
    When hydrochloric acid reacts with calcium carbonate, we will see gas bubbles rising. This is carbon dioxide gas produced during the reaction. At the same time, the solid calcium carbonate will gradually disappear, replaced by a solution of calcium chloride.
