What is acid rain short note?
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
What is acid rain PPT?
Formation of Acid Rain When water vapour condenses, or as the rain falls, they dissolve in the water to form sulphuric acid (H2SO4) and nitric acid (HNO3). While the air in cleaned of the pollutants in this way, it also causes precipitation to become acidic, forming acid rain.
What is acid rain introduction?
Acid rain is formed when chemicals such as sulfur dioxide (SO2) or nitrogen oxides (NOx) react with water in the atmosphere to form mild solutions of sulfuric or nitric acid. Forests and vegetation – Acid rain damages trees and the increased aluminum in the soil inhibits the uptake of water.
What is acid rain and its effects?
What is acid rain and how is it caused? Acid rain is caused by a chemical reaction that begins when compounds such as sulphur dioxide and oxides of nitrogen are released into the air.
What is acid rain Ncert?
Answer: Pollutants like sulphur dioxide and nitrogen dioxide liberated into the air by industries reacts with water vapour in air to form sulphuric acid and nitric acid. These acids come down as rain, called acid rain.
What is the history of acid rain?
Acid rain. It began in the 1950s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds–and rainfall–acidic. As acid rain fell, it affected everything it touched, leaching calcium from soils and robbing plants of important nutrients.
What is the conclusion of acid rain?
Conclusion: To conclude, acid rain is very important issue that has bad effects in the environment. There would be many health problems that could be avoided, if acid rain became a little less of a problem. We can help to stop this acid rain by a very simple way which is not polluting the air.
What is acid rain long answer?
Acid rain is rain that is unusually acidic and highly corrosive in nature. It may be defined as “rain water having pH less than 5.6”. Acid rain can have harmful effects on plants, animals and humans. It is caused when gaseous compounds of ammonium, carbon, nitrogen, and sulphur are released into the atmosphere.
What is acid rain kid definition?
Acid rain is a form of air pollution. When coal and petroleum are burned in automobiles, electric power plants, and factories, they release certain harmful gases into the air. When the water in the air comes down as rain, sleet, hail, or snow, it carries with it these gases. This is known as acid rain.
What is acid rain class 9 science?
When sulfur dioxide (SO2) and nitrogen oxides NOx are released into the atmosphere and transported by wind and air currents, acid rain is produced. (SO2) and NOx react with water, oxygen and other chemicals to form sulfuric acid and nitric acid. Complete solution: The pH of acid rain is not enough to burn human skin.
What are the disadvantages of acid rain?
Acid rain causes the foliar damage to crops as well as acidification of soil. Aquatic systems are affected by this acid rain. The most important disadvantage of acid rain is that it is corrosive to exposed metals like rails. Some buildings are also affected by this acid rain.
Is acid rain different from regular rain?
The key difference between acid rain and normal rain is that acid rain contains a large amount of sulfur dioxide and nitrogen oxide gases dissolved in it than the normal rain . Usually, the atmosphere contains acidic gases from natural processes. The key difference between acid rain and normal rain is that the acid rain contains a large amount of sulfur dioxide and nitrogen oxide gases dissolved in it than the normal rain. Reference:
What is a simple explanation of acid rain?
Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components , such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
Acid rain has many ecological effects, but none is greater than its impact on lakes, streams, wetlands, and other aquatic environments. Acid rain makes waters acidic, and causes them to absorb the aluminum that makes its way from soil into lakes and streams.
