Hydrochloric acid (HCl) reacts with magnesium carbonate (MgCO3) to form carbon dioxide. In fact, any acid will react with any carbonate to form CO2. Two hydrogen ions (positively charged) will become interested in the negatively charged carbonate (CO3-2), and one oxygen atom will dissociate from the carbonate (taking both extra electrons!) to bind with the hydrogens to form water. The carbonate is now CO2 and will escape the beaker as a gas. The equation is:
2HCl + MgCO3 ---> MgCl2 + H2O + CO2(g)
Magnesium Carbonate + Hydrochloric Acid ------> Magnesium Chloride + Water + Carbon Dioxide The previous answer said magnesium hydroxide + carbon dioxide, but then you will have canceled out the chlorine, which due to the law of conservation of mass, is impossible.
Magnesium Chloride. MgCO3 +2HCl -----> MgCl2 + CO2 + H2O
The balanced chemical equation for the reaction between magnesium carbonate (MgCO3) and hydrochloric acid (HCl) is: MgCO3 + 2HCl -> MgCl2 + H2O + CO2
When more magnesium carbonate is added to hydrochloric acid and the fizzing stops, it could mean that all the acid has reacted with the magnesium carbonate to form magnesium chloride, carbon dioxide, and water. This reaction consumes the acid, causing the fizzing to cease.
When hydrochloric acid reacts with magnesium carbonate, magnesium chloride, carbon dioxide, and water are formed. The resulting solution will be acidic due to the presence of hydrochloric acid and the formation of magnesium chloride. The pH will depend on the concentrations of the reactants and products, but typically it will be less than 7 due to the presence of the strong acid.
Magnesium Carbonate
Magnesium chloride is formed.
When hydrochloric acid and magnesium carbonate react, they produce magnesium chloride, carbon dioxide, and water. The balanced chemical equation for this reaction is: 2HCl + MgCO3 → MgCl2 + CO2 + H2O.

carbon dioxide
The balanced chemical equation for the reaction between magnesium carbonate (MgCO3) and hydrochloric acid (HCl) is: MgCO3 + 2HCl -> MgCl2 + H2O + CO2
Carbon Dioxide
The products that are formed will be magnesium salt, water and carbon dioxide. Exactly what salt is made depends the acid used. Hydrochloric acid produces magnesium chloride; sulphuric acid produces magnesium sulphate; nitric acid produces magnesium nitrate.
The products are calcium and magnesium chlorides, water and carbon dioxide.
When more magnesium carbonate is added to hydrochloric acid and the fizzing stops, it could mean that all the acid has reacted with the magnesium carbonate to form magnesium chloride, carbon dioxide, and water. This reaction consumes the acid, causing the fizzing to cease.
The gas carbon dioxide is released.
