Acid Rain - Department of Chemistry

This process occurs at the surface of the buildings or monuments; thus acid rain can easily destroy the details on relief work (e.g., the faces on a statue), but generally does not affect the structural integrity of the building. The degree of damage is determined not only by the acidity of the rainwater, but also by the amount of water flow ...

Acid Rain - USGS

Acid rain is the term commonly used by scientists to describe rain that is abnormally acidic. What does that mean? Well, plain distilled water, like that used in laboratories, is neutral (not acidic or basic). Since rain naturally has things dissolved in it, it will always be slightly acidic.

Doesn't CO2 contribute to acid rain? - Quora

Answer (1 of 4): Carbon dioxide in the air can dissolve in rain water to form carbonic acid, H2CO3. Carbonic acid is a weak acid. It partially ionises to form hydrogen ions. The hydrogen ions from carbonic acid give natural rain water a slightly acid pH value of 5.6. For this reason, technically...

Limestone and Acid Rain

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.

Acid rain results when sulfur dioxide (SO 2) and nitrogen oxides (NO X) are emitted into the atmosphere and transported by wind and air currents.The SO 2 and NO X react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground. While a small portion of the SO 2 and NO X that cause acid rain is from ...
