Understanding Pyrites Ore
Pyrites, or iron sulfide (FeS2), is a mineral commonly found in nature. When pyrites ore is heated or burned, a chemical reaction occurs, primarily releasing sulfur dioxide gas.
Process of Burning Pyrites
- When pyrites ore is subjected to high temperatures, it undergoes oxidation.
- The sulfur present in the ore reacts with oxygen in the air.
- This reaction predominantly produces sulfur dioxide (SO2) as a byproduct.
Why Sulfur Dioxide?
- Sulfur dioxide is a colorless gas with a pungent odor.
- It is a significant pollutant and contributes to environmental issues such as acid rain.
- The reaction can be summarized as:
- 4 FeS2 + 11 O2 → 8 SO2 + 4 FeO
Environmental Impact
- Burning pyrites contributes to air pollution.
- Sulfur dioxide can lead to respiratory problems for humans and animals.
- It also reacts with water vapor in the atmosphere, forming sulfuric acid, which is harmful to ecosystems.
Conclusion
In conclusion, burning pyrites ore primarily emits sulfur dioxide gas, making option 'B' the correct answer. Understanding this reaction is crucial for addressing environmental concerns and managing sulfur emissions effectively.
