How does the pH of an acidic solution compare to that of a neutral solution?

A. The pH of an acidic solution is lower than that of a neutral solution

B. The pH of an acidic solution is higher than that of a neutral solution

C. The pH of an acidic solution is the same as that of a neutral solution

D. The pH of an acidic solution is unpredictable

Answer Explanation:

The pH scale ranges from 0 to 14, where pH values less than 7 indicate acidic solutions. Therefore, the pH of an acidic solution is lower than that of a neutral solution, which has a pH of 7.

Therefore, the Correct Answer is A.
