Limestone and Acid Rain

Acid rain causes acidification of lakes and streams and contributes to the damage of trees at high elevations and sensitive forest soils. Effect of Limestone Calcium carbonate, [Ca][CO 3] is a very common mineral. 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 ...

What happens when acid reacts with limestone?

15/06/2008  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

What Does Acid Rain Do to Limestone? eHow

Acid rain has a direct effect on limestone rocks that occur in soil, below ground and on buildings. Chemical Reaction Three common acids that form in the atmosphere are carbonic acid that forms from carbon dioxide, nitric acid that forms from nitrous oxide and sulfuric acid that forms from sulfur dioxide. Acid rain may form with water as a liquid, or as dry and gaseous forms of the acids that ...

Why are Limestone structures eroded by acid rain? MyTutor

When this rain water falls it reacts with the claim carbonate present in limestone, in the following reaction: Calcium carbonate + carbonic acid -> Calcium Salt + Water + CO2 This reaction has been responsible for the natural formation of limestone caves over millions of years, but more recently more acidic rain has been produce by the excess Sulfur Dioxide produced by burning Coal.

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.

Limestone Neutralization: When acid rain falls to the earth, it undergoes a new round of physical and chemical changes. These changes may reduce the acidity and change the chemical characteristics of the water reaching the streams and lakes. Alkaline or basic soils, such as those rich in limestone, calcium carbonate, can neutralize the acid directly. These types of soils are found in the ...

How Does Acid Rain Affect Buildings Statues? Sciencing

Before people became aware of the problems that acid rain caused, they often used metals, limestone and marble as building materials exposed to rain and fog. Some of these materials contain calcium carbonate or calcium-based compounds, which can be dissolved by acid rain. Sandstone holds up better to acid rain, but can be marred by black surface deposits over time.
