The pH value of a solution is 5.9. If the hydrogen ion concentration is decreased hundred times, the solution will be______________?
Correct answer: A. Basic
- A. Basic
- B. More acidic
- C. Neutral
- D. Of the same acidity
Explanation
Reducing hydrogen-ion concentration by 100 increases pH by 2 units, from 5.9 to 7.9. Since the final pH is above 7, the solution is basic.
