Does Magnesium Carbonate mix with Hydrochloric acid to form a precipitate or anything?
magnesium carbonate is not very soluble in water, so it would start as a “precipitate”. It would dissolve in the hydrochloric acid to give a clear solution of magnesium chloride, and carbon dioxide would be given off as a gas. So you would see the solid magnesium carbonate disappear into solution and bubbles of carbon dioxide.
