  • What happens when acid reacts with limestone Questions

    Jun 15 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble so rocks don t dissolve very quickly. But if you add an acid you add hydrogen ions (H ) which will react with the carbonate to form hydrogen carbonate HCO3- ions which are very soluble in water and the limestone will dissolve. Or if there is more acid two hydrogen ions will
