What is acid rain and its effects?
Effects of Acid Rain on Plants and Trees Dead or dying trees are a common sight in areas effected by acid rain. Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.
What is acid rain describe its effect in 150 words?
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 give its effects in short?
When the accumulated acids are washed off a surface by the next rain, this acidic water flows over and through the ground, and can harm plants and wildlife, such as insects and fish. The amount of acidity in the atmosphere that deposits to earth through dry deposition depends on the amount of rainfall an area receives.
What happens if acid rain touches you?
Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this, never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air. Unpolluted rain would have a pH value of between 5 and 6.
How long has acid rain been a problem?
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.
What problems does acid rain cause?
Acid Rain Can Cause Health Problems in People Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Respiratory diseases like asthma or chronic bronchitis make it hard for people to breathe.
Where does acid rain mostly occur?
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.
What is the color of acid rain?
When you add acid, bromothymol blue turns yellow; when you add a base (like sodium sulfite), it turns blue.
How do we make acid rain?
How can you identify acid rain?
To know if a sample of rain is “acid rain” we need to measure the concentration of hydrogen ions in the sample. Hydrogen ions are produced when any acidic substance is dissolved in water. The solutions of some substances, like carbon dioxide in the air, are weakly acidic.
What are the effects of acid rain Class 9?
Effects of Acid Rain It causes respiratory issues in animals and humans. When acid rain falls down and flows into the rivers and ponds it affects the aquatic ecosystem. As it alters the chemical composition of the water, to a form which is actually harmful to the aquatic ecosystem to survive and causes water pollution.
How is acid rain caused Class 9?
Acid rain is caused by the release of the gases like SO2 (sulphur dioxide) and NO2 (nitrogen dioxide) released from the emission of vehicles and combustion of fuels. These gases dissolve in rain water to form nitric acid and sulphuric acid.
What will be the pH value of acid rain?
Normal, 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.
Is acid rain safe to drink?
Humans are affected when we breathe in air pollution, this can cause breathing problems, and even cancer. Drinking water which has been contaminated with acid rain can cause brain damage over time.
What are the 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.
How Taj Mahal is affected by acid rain?
Effects of acid rain on Taj Mahal Taj Mahal is completely made of marble, acid rains reacts with marble to form a powder-like substance which is then washed away by the rain. This phenomenon is called marble cancer. Sulphur and nitrogen oxide are the main pollutants which react with air to form acids.
What is the pH of acid rain?
4.0
