What Is Calcium Carbonate's Reaction With Hydrochloric

Both of these compounds are ionic, with a hydrogen ion bound to a chloride ion in hydrochloric acid and a calcium ion bound to a carbonate group in calcium carbonate The carbonate group is actually covalently bonded carbon and oxygen, but the calcium carbonate as a whole is ionic Two chloride ions bond to one calcium ion.
