Understanding Acid Rain
Acid rain is a significant environmental issue that affects ecosystems and human structures. The term refers to precipitation that has a lower pH than normal rainwater, making it acidic.
Causes of Acid Rain
- Oxides of Nitrogen and Sulfur: The primary contributors to acid rain are the oxides of nitrogen (NOx) and sulfur (SOx). These gases are emitted from various sources, including vehicles, industrial processes, and power plants.
- Dissolution in Rain: When these oxides are released into the atmosphere, they react with water vapor, oxygen, and other compounds. This reaction leads to the formation of nitric acid (HNO3) and sulfuric acid (H2SO4), which then mix with raindrops.
Role of Carbon Dioxide
- Carbonic Acid Formation: While carbon dioxide (CO2) does dissolve in rainwater to form carbonic acid (H2CO3), the impact is minimal compared to the acids produced from NOx and SOx. Carbonic acid is weak and does not significantly lower the pH of rainwater.
- Comparison with Strong Acids: In contrast, nitric and sulfuric acids are much stronger and have a more pronounced effect on the acidity of rain.
Conclusion
Considering these factors, the correct answer is option 'B'. The significant contributors to acid rain are indeed the oxides of nitrogen and sulfur, which form respective strong acids upon dissolution in rainwater. Understanding these processes helps us appreciate the complexity of environmental chemistry and the importance of reducing emissions to mitigate acid rain's effects.
