How does acid precipitation affect marble and limestone

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.

Acid rain Effects on human-made structures Britannica

Acid deposition also affects human-made structures. The most notable effects occur on marble and limestone, which are common building materials found in many historic structures, monuments, and gravestones. Sulfur dioxide, an acid rain precursor, can react directly with limestone in the presence of water to form gypsum, which eventually flakes off or is dissolved by water.

What Does Acid Rain Do to Limestone? eHow

One of the most noticeable effects of acid rain is on limestone blocks that are part of a building or statue. Over time, the acid rain will round the edges of statues and pit the flat surfaces of the rock. Another common reaction is the production of gypsum on the surface of the limestone that comes in contact with sulfuric acid.

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
