Quick Answer: What Is Acid Rain PPT?

What is acid rain Slideshare?


Acid rain By: Dhirendra Nath.


Introduction • Acid rain is basically rain that has a higher than normal acid level (low pH,pH of less than 5.6 ).

 Acid rain is otherwise known as the phenomenon of abnormally acidic precipitation, e.g.

Rain, hail, snow ,fog , frost, and dry as dust..

What are 3 causes of acid rain?

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 are 3 effects of acid rain?

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

What are 3 possible ways to reduce acid rain?

A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.

Can acid rain kill you?

The harm to people from acid rain is not direct. … Walking in acid rain, or even swimming in an acid lake, is no more dangerous than walking or swimming in clean water. However, the pollutants that cause acid rain—sulfur dioxide (SO2) and nitrogen oxides (NOx)—do damage human health.

What is acid rain explain briefly?

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.

What are the types of acid rain?

Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry. When fossil fuels such as coal, gasoline, and oil are burned, they release the gases sulfur dioxide and nitrogen oxide.

Why Acid rain is harmful?

Acid Rain Harms Forests Acid rain can be extremely harmful to forests. Acid rain that seeps into the ground can dissolve nutrients, such as magnesium and calcium, that trees need to be healthy. Acid rain also causes aluminum to be released into the soil, which makes it difficult for trees to take up water.

What pH is acid rain?

4.0Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. 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 4.0.

When has acid rain happened in the past?

Acid rain was first identified in North America at Hubbard Brook in the mid-1960s, and later shown to result from long-range transport of sulfur dioxide and nitrogen oxides from power plants. Hubbard Brook research influenced national and international acid rain policies, including the 1990 Clean Air Act amendments.

Where is acid rain?

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.

How can we make acid rain at home?

Pour 1/4 cup of vinegar or lemon juice into the jar then fill the rest of the jar with tap water. Label one plant “a little acid.” Make two labels that say “a lot of acid.” Put a label on the second jar. Pour 1 cup of vinegar or lemon juice into the second jar then fill the rest of the jar with tap water.

What is acid rain formula?

Sulfuric Acid ( H2SO4 ) Sulfuric acid forms from sulfur dioxide ( SO2 ). This occurs naturally though volcanic eruptions (or the release of volcanic gases). Humans contribute to the release of SO2 through combustion of fossil-fuels. The initial equation looks like this: SO2+OH⋅→HOSO2⋅
