Acidic rain, also known as acid rain, is a type of precipitation that has a higher than normal acidity level. This is typically caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric acid and nitric acid. Acid rain can have harmful effects on the environment, including damaging forests, lakes, and buildings, as well as harming aquatic life and soil quality. Efforts to reduce the emissions of these pollutants have helped to decrease the occurrence of acid rain in many regions.

Definition:
Acidic rain is a form of precipitation that contains high levels of acids, primarily sulfuric acid (H2SO4) and nitric acid (HNO3).
Causes:
Air pollution from human activities, particularly the combustion of fossil fuels that release sulfur dioxide (SO2) and nitrogen oxides (NOx), is the primary cause of acidic rain. These gases react with water vapor in the atmosphere, forming sulfuric acid and nitric acid.
Formation:
- Combustion: Fossil fuel combustion in power plants, industries, and vehicles releases sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.
- Oxidation: In the presence of sunlight, SO2 and NOx undergo chemical reactions to form sulfur trioxide (SO3) and nitrogen dioxide (NO2).
- Dissolution: SO3 and NO2 dissolve in water droplets in clouds, forming sulfuric acid (H2SO4) and nitric acid (HNO3).
Effects of Acidic Rain:
- Environmental:
- Acidifies lakes, streams, and soil, harming aquatic life and terrestrial ecosystems.
- Damages forests and crops.
- Corrodes buildings, statues, and other structures.
- Human Health:
- Respiratory problems, such as asthma and bronchitis.
- Eye irritation and skin rashes.
Mitigation Measures:
- Reducing Fossil Fuel Combustion: Transitioning to renewable energy sources, increasing fuel efficiency, and reducing energy consumption.
- Air Pollution Control: Installing scrubbers and catalytic converters on power plants and industries to remove sulfur dioxide and nitrogen oxides from emissions.
- Liming: Adding alkaline materials, such as limestone, to acidified lakes and streams to neutralize the acidity.
Monitoring and Regulation:
- Monitoring: Monitoring stations measure the pH level of precipitation to track the extent of acidic rain.
- Regulation: Governments impose regulations and standards to limit the emission of sulfur dioxide and nitrogen oxides.
