Jun 14, 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

and N02 has a corrosive effect on calcareous stone materials (Johansson et aI., 1988). The total corrosive effect of acid rain cannot be determined unequivocally since it has both corrosive and washing effects. Thus in heavily polluted industrial air the corrosion rate on the upper side of steel panels was only 37% of the total corrosion.
