The equation BaCO3 + 2HCl -> BaCl2 + H2O + CO2

  1. Detailed information about the chemical equation BaCO3 + 2HCl -> BaCl2 + H2O + CO2:

    • The above chemical equation describes the chemical reaction between barium carbonate (BaCO3) and hydrochloric acid (HCl) to produce barium chloride (BaCl2), water (H2O), and carbon dioxide gas (CO2).
    • BaCO3, HCl, BaCl2, H2O, and CO2 are the chemical formulas of the substances involved in the reaction. The numbers 1, 2 represent the mole ratio between the substances in the reaction.

  2. Reaction conditions:

    • The reaction occurs at room temperature.
    • BaCO3 must be in powder form to increase the contact surface area with HCl.

  3. Reaction process:

    • Barium carbonate (BaCO3) reacts with hydrochloric acid (HCl) to form barium chloride (BaCl2), water (H2O), and carbon dioxide gas (CO2).
    • This is an acid-base substitution reaction, where the hydrochloric acid substitutes the carbonate ion in the barium carbonate to form barium chloride.

  4. Occurring phenomena:

    • When acid is poured into the barium carbonate powder, a chemical reaction will occur and carbon dioxide gas bubbles will be produced.
    • When the reaction is complete, we will observe water and barium chloride dissolved in water.
