What Does Acid Rain Do To Marble

What effect does acid rain have on marble.

What does acid rain do to marble. Acid precipitation affects stone primarily in two ways. Stone surface material may be lost all over or only in spots that are more reactive. Students know buffers stabilize ph in acid base reactions. In the atmosphere rain mixes with carbon dioxide nitrous oxide and sulfuric dioxide to form acid rain.

Students know how to calculate ph from hydrogen ion concentration. Effects of acid rain on materials. It is well established that either wet or dry deposition of sulfur dioxide significantly increases the rate of corrosion on limestone sandstone and marble. These constituents may occur naturally from processes such as volcanic eruptions and the oxidation of rocks or their presence in.

When sulfurous sulfuric and nitric acids in polluted air react with the calcite in marble and limestone the calcite dissolves. Acid rain effects on buildings. How does acid precipitation affect marble and limestone buildings. Not all acidic deposition is wet sometimes dust particles can become acidic as well and this is called dry deposition when acid rain and dry acidic particles fall to earth the nitric and sulfuric acid that make the particles acidic can land on statues buildings and other manmade structures and damage their surfaces.

Acids have a corrosive effect on limestone or marble buildings or sculptures. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.
