The equation FeCO3 + HCl -> FeCl2 + CO2 + H2O

  1. Detailed information about the chemical equation:

    • In this equation, iron carbonate (FeCO3) reacts with hydrochloric acid (HCl) to form iron (II) chloride (FeCl2), carbon dioxide gas (CO2) and water (H2O).
    • The complete and balanced chemical equation: FeCO3 + 2HCl -> FeCl2 + CO2 + H2O

  2. Reaction conditions:

    • This reaction occurs at room temperature and normal pressure. No other special conditions are required.

  3. Reaction process:

    • When iron carbonate (FeCO3) reacts with hydrochloric acid (HCl), it forms iron (II) chloride (FeCl2), carbon dioxide gas (CO2), and water (H2O).
    • The reaction process will stop when one of the two reactants is exhausted.

  4. Phenomena occur:

    • When hydrochloric acid is added to iron carbonate, gas bubbles appear. This is the carbon dioxide gas produced during the reaction.
    • If this reaction takes place in a solution, the color of the solution may change from the white of iron carbonate to the light green of iron (II) chloride.
