The Contact process is the modern industrial method for producing which acid?
Correct answer: C. Sulfuric acid (H₂SO₄)
- A. Hydrochloric acid (HCl)
- B. Nitric acid (HNO₃)
- C. Sulfuric acid (H₂SO₄)
- D. Acetic acid (CH₃COOH)
Explanation
The Contact process is the main method for producing sulfuric acid. It involves catalytically oxidizing sulfur dioxide (SO₂) to sulfur trioxide (SO₃), which is then absorbed into concentrated sulfuric acid.
