Here's how it works:
* Sulfur dioxide and nitrogen oxides are released into the atmosphere primarily from burning fossil fuels (like coal and oil) in power plants, factories, and vehicles.
* When these gases react with water, oxygen, and other chemicals in the air, they form sulfuric acid (H2SO4) and nitric acid (HNO3).
* These acids then dissolve in rainwater, making it acidic.
Important Note: While sulfur dioxide and nitrogen oxides are the primary culprits, other gases can contribute to acid rain, including:
* Ammonia (NH3): Can react with sulfuric and nitric acid, forming ammonium sulfate and ammonium nitrate, which also contribute to acid rain.
* Carbon dioxide (CO2): While not directly responsible for acid rain, CO2 dissolved in rainwater can make it slightly acidic.
It's crucial to understand that acid rain is a complex phenomenon resulting from the interaction of various gases and chemicals.
