Which of the following acids is the main component of acid mine drainage?
Correct answer: C. H2SO4
- A. HCl
- B. HNO3
- C. H2SO4
- D. CH3COOH
Explanation
Acid mine drainage is formed when sulfide minerals (like pyrite, FeS2) present in coal and metal ores are exposed to air and water. This triggers their oxidation, a process that produces sulfuric acid (H2SO4), leading to highly acidic wastewater.
