Does Calcium Carbonate Dissolve in Water?
Answer:Calcium carbonate(CaCO₃) is an ionic compound.So it should have dissolve in water but calcium carbonate does not dissolve in pure water.But calcium carbonate dissolve in slightly acidic water like rain water,river water etc.
Explanation:
Calcium carbonate (CaCO₃) is nothing but limestone.CaCO₃ is not soluble in water but it does dissolve a solvent which is weakly acidic.
Surface water is somewhat acidic in nature because the CO₂ of air dissolves in rain and produce carbonic acid(H₂CO₃)
CO₂ +H₂O =H₂CO₃
Acidic surface water converts insoluble calcium carbonate to soluble calcium hydrogen carbonate.
CaCO₃ +Acidic H₂O (H2O+CO2) >>Ca(HCO₃)₂
