【●】Does Calcium Carbonate Dissolve in Water?||Is Calcium Carbonate Soluble in Water
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 ●What does calcium carbonate dissolve ? Ans: Vinegar or acidic water can dissolve calcium carbonate. ●Calcium carbonate in water? Ans: Calcium carbonate does not dissolve in pure water.But acidic water can dissolve calcium carbonate. ...
