Oct 15, · Acid rain is more acidic than normal rain and forms through a complex process of chemical reactions involving air pollution and water molecules in the air. The two most important pollutants that contribute to the formation of acid rain are nitrogen and sulfur compounds, which react with moisture in the atmosphere to form nitric and sulfuric acid The Acid Rain Program is a market-based initiative taken by the United States Environmental Protection Agency in an effort to reduce overall atmospheric levels of sulfur dioxide and nitrogen oxides, which cause acid rain. The program is an implementation of emissions trading that primarily targets coal-burning power plants, allowing them to buy and sell emission permits Jul 14, · Acid rain is any form of precipitation that contains acidic components, such as sulfuric or nitric acid. Acid rain affects nearly everything: plants, soil,
Acid Rain: Scourge of the Past or Trend of the Present? | NSF - National Science Foundation
The pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero the most acidic to 14 the most basic. As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic. Normal, clean rain has a pH value of between 5. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic.
Typical acid rain has a pH value of 4. A decrease in pH values from 5. There are many high-tech devices that are used to measure pH in laboratories, term paper about acid rain. One easy way that you can measure pH is with term paper about acid rain strip of litmus paper. When you touch a strip of litmus paper to something, the paper changes color depending on whether the substance is acidic or basic.
If the paper turns red, the substance is acidic, and if it turns blue, the substance is basic. Acid Rain and the pH Scale The pH scale measures how acidic an object is.
How pH is Measured There are many high-tech devices that are used to measure pH in laboratories, term paper about acid rain.

Mar 04, · Effects of acid rain on aquatic life. The action of acid rain causes harmful elements like mercury and aluminium to be leached from the soil and rocks and it is then carried into the lakes where aquatic life may be affected. Warning signs have been posted at several lakes, telling about the dangers of eating fish which may have been poisoned by mercury. Just July 25, Find related stories on NSF's Long-Term Ecological Research Program at this link.. Acid rain. It was a problem that largely affected U.S. eastern states. It began in the s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds--and rainfall--acidic Acid rain: why it is a concern—March Ecosystems Acid rain has had major ecological consequences in other parts of the world. Some lakes in countries such as Sweden have become so acidic, from acid rain resulting from pollution in other countries, that they are no longer able to support fish life
