A pH of _____ is neither an acid nor a base.
- A.
1
- B.
5
- C.
7
- D.
8
Correct Answer
C. 7Explanation
A pH of 7 is considered neutral because it is right in the middle of the pH scale, which ranges from 0 to 14. A pH of 7 indicates that the substance is neither acidic nor basic, meaning it is neither releasing hydrogen ions (H+) nor hydroxide ions (OH-). This is often seen in pure water, which has an equal concentration of H+ and OH- ions, resulting in a neutral pH of 7.Rate this question:
