Acid Rain's Slow Dissolve - National Mall and Memorial ...

Remember acid rain? Ever wondered if it's still around? Acid rain has not gone away, but it has gotten somewhat better. Acid rain is a threat to both natural areas and to our national monuments and memorials. Many monuments are made from limestone, marble, and bronze-materials that can be altered or slowly dissolved by acid precipitation.

Limestone and Acid Rain - University Of Illinois

Limestone is one familiar form of calcium carbonate. Acids in acid rain promote the dissolution of calcium carbonate by reacting with the carbonate anion. This produces a solution of bicarbonate. Because surface waters are in equilibrium with atmospheric carbon dioxide there is a constant concentration of carbonic acid, H 2 CO 3, in the water.

The Effects of Acid Rain - Activity - TeachEngineering

Chalk, composed of limestone, represents statues in this activity. Limestone contains calcium carbonate (CaCO 3), which reacts chemically with acids, causing it to deteriorate or erode. The acid causes the calcium (Ca) and carbonate (CO 3) in the limestone to separate into calcium and carbon dioxide gas (CO 2).

It is dense and durable. Limestone is a sedimentary rock comprised mainly of the mineral calcite and formed through the compression of mostly marine organisms in pre-historic times. It can be soft and flinty and porous and, though easy to cut and tool, it is susceptible to weathering from the effects of acid rain and other pollutants.

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.

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.
