Acid Rain
Acid rain is a form of precipitation that contains high levels of acidic components, such as sulfuric acid (H₂SO₄) and nitric acid (HNO₃). It occurs when sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) are released into the atmosphere through natural processes like volcanic eruptions and forest fires, as well as human activities such as burning fossil fuels, industrial emissions, and vehicular exhaust. These pollutants react with water vapor, oxygen, and other atmospheric chemicals to form acidic compounds, which then mix with rain, snow, fog, or dust and fall to the Earth’s surface.
The pH of normal rainwater is around 5.6 due to the presence of dissolved carbon dioxide (CO₂), which forms carbonic acid (H₂CO₃). However, in acid rain, the
