The pollutants most commonly attributed to acid rain are sulfur dioxide (SO2) and nitrogen dioxide (N O2). SO2 and N O2 are released from factories in gaseous form into the atmosphere, where they mix with water (H 2O) and hydroxides (OH ⋅) which are normally present.

What is the cause 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 happens if precipitation becomes too acidic?
However, if precipitation becomes too acidic, these materials may not be able to neutralize all of the acids. Over time, these neutralizing materials can be washed away by acid rain. Damage to crops, trees, lakes, rivers, and animals can result.
Is rain acidic or non acidic?
Nature depends on balance, and although some rain is naturally acidic, with a pH level of around 5.0, human activities have made it worse. Normal precipitation —such as rain, sleet, or snow—reacts with alkaline chemicals, or non-acidic materials, that can be found in air, soils, bedrock, lakes, and streams.
What is the result of acid rain?
Acid rain results when sulfur dioxide (SO 2) and nitrogen oxides (NO X) are emitted into the atmosphere and transported by wind and air currents. The SO 2 and NO X 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 is 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.
How does acidic water affect the environment?
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.
Where does acid rain come from?
While a small portion of the SO 2 and NO X that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels. The major sources of SO 2 and NO X in the atmosphere are: Burning of fossil fuels to generate electricity.
Is rain acidic or alkaline?
The lower a substance's pH (less than 7), the more acidic it is; the higher a substance's pH (greater than 7), the more alkaline it is. Normal rain has a pH of about 5.6; it is slightly acidic because carbon dioxide (CO 2) dissolves into it forming weak carbonic acid. Acid rain usually has a pH between 4.2 and 4.4.
What causes acid rain?
The main sources of pollutants that trigger acid rain are vehicles and industrial and power-generating plants. The areas of greatest acidity are in the northeastern United States.
How does acid rain affect the environment?
IMPACT OF ACID RAIN ON FORESTS. Acid rain can dissolve certain more soluble elements from the soil, like aluminum. The dissolved aluminum begins to accumulate and can reach toxic levels as it enters local streams and wetlands. Acid rain also removes important nutrients from the soil, such as calcium, potassium, and magnesium.
What is the National Acid Precipitation Assessment Program?
The National Acid Precipitation Assessment Program (NAPAP), a Federal program involving representatives from more than a dozen Federal agencies, has sponsored studies on how acid rain forms and how it affects lakes, crops, forests, and materials.
What is acid rain?
Acid rain is the term commonly used by scientists to describe rain that is abnormally acidic. What does that mean? Well, plain distilled water, like that used in laboratories, is neutral (not acidic or basic). Since rain naturally has things dissolved in it, it will always be slightly acidic.
What are the hazards of volcanic air pollution in Hawaii?
Volcanic air pollution hazards in Hawaii. Noxious sulfur dioxide gas and other air pollutants emitted from Kīlauea Volcano on the Island of Hawai‘i react with oxygen, atmospheric moisture, and sunlight to produce volcanic smog (vog) and acid rain.
Why are historic buildings affected by acid rain?
Because buildings and monuments cannot adapt to changes in the environment, as plants and animals can, historic structures may be particularly affected by acid precipitation. Scientists are studying effective control technologies to limit the emissions from power plants and automobiles that cause acid rain.
Why are forests more susceptible to pests, disease, and injury from freezing and drought?
Lastly, the combination of reduced calcium and excessive aluminum can make forests more susceptible to pests, disease, and injury from freezing and drought, as a proper balance of these nutrients is vital to forest health. A forest of dead trees damaged by acid rain (Credit: Pixabay).
Causes of Acid Rain
Acid rain is caused by many different things, such as burning fossil fuels and the use of aerosols.

How does acid rain affect ecosystems?
The Effects of Acid Rain on Ecosystems. This figure illustrates the pH level at which key organisms may be lost as their environment becomes more acidic. Not all fish, shellfish, or the insects that they eat can tolerate the same amount of acid. An ecosystem is a community of plants, animals and other organisms along with their environment ...
What happens to trees when they get acid rain?
Acid rain also removes minerals and nutrients from the soil that trees need to grow. At high elevations, acidic fog and clouds might strip nutrients from trees’ foliage, leaving them with brown or dead leaves and needles.
What is episodic acidification?
Episodic Acidification. Melting snow and heavy rain downpours can result in what is known as episodic acidification. Lakes that do not normally have a high level of acidity may temporarily experience effects of acid rain when the melting snow or downpour brings greater amounts of acidic deposition and the soil can’t buffer it.
What gases can be transformed into sulfate and nitrate particles?
In the atmosphere, SO 2 and NO X gases can be transformed into sulfate and nitrate particles, while some NO X can also react with other pollutants to form ozone. These particles and ozone make the air hazy and difficult to see through.
What happens when acidic particles corrode metal?
The acidic particles corrode metal and cause paint and stone to deteriorate more quickly. They also dirty the surfaces of buildings and other structures such as monuments. The consequences of this damage can be costly: loss of detail on stone and metal statues, monuments and tombstones.
What are the effects of sulfur dioxide on the heart?
Many scientific studies have shown a relationship between these particles and effects on heart function, such as heart attacks resulting in death for people with increased heart disease risk, and effects on lung function, such as breathing difficulties for people with asthma. Learn more about: Sulfur Dioxide. Nitrogen Oxides.
Does acid rain cause pollution?
Nitrogen Pollution. It’s not just the acidity of acid rain that can cause problems. Acid rain also contains nitrogen, and this can have an impact on some ecosystems. For example, nitrogen pollution in our coastal waters is partially responsible for declining fish and shellfish populations in some areas.
