What is an example of acid rain?
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX 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.
What neutralizes acid rain?
Limestone Neutralization: Alkaline or basic soils, such as those rich in limestone, calcium carbonate, can neutralize the acid directly.
Where is acid rain most serious?
Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States, and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan.
What human activities causes acid rain?
Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
What are the benefits of acid rain?
In fact, the greatest benefits are the 20,000 to 50,000 lives saved per year because of cleaner air and lower pollution levels. SO2 and NOx emissions can lead to the formation of fine particle pollution and smog, also called ground level ozone.
How can you tell if its acid rain?
To measure the potency of acid rain, scientists test the pH of collected cloud water. The pH tests show how acidic or basic something is. The pH scale rules from 0 to 14. Seven represents levels that are neutral, while lower numbers are more acidic and higher numbers are more basic.
What are the harmful effects of acid rain Class 8?
(1) Acid rain causes direct damage to leaves of plants. (2) Acid rain causes damage to fresh water life which decreases the fish population in lakes. (4) Acid rain removes basic nutrients such as calcium from the soil.
What is the difference between acid rain and normal rain?
Acid rain describes any form of precipitation that contains high levels of nitric and sulfuric acids. It can also occur in the form of snow, fog, and tiny bits of dry material that settle to Earth. Normal rain is slightly acidic, with a pH of 5.6, while acid rain generally has a pH between 4.2 and 4.4.
Where is acid rain a problem?
Acid rain is responsible for severe environmental destruction across the world and occurs most commonly in the North Eastern United States, Eastern Europe and increasingly in parts of China and India.
