pH value of H2SO4 (5% concentration) is__________________?
Correct answer: C. < 7
- A. 5
- B. 7
- C. < 7
- D. > 7
Explanation
Sulfuric acid produces hydrogen ions in water, making the solution acidic regardless of its stated concentration. An acidic solution has a pH below 7, so the correct choice is d.
