Jun 15, 2008 0183 32 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 ,...
