What range of pH values is considered acidic?

0-7
7
7-14
None of the above

The correct answer is: 0-7

pH is a scale used to measure the acidity or alkalinity of a solution, ranging from 0 to 14. A pH value of 7 is considered neutral, meaning the solution is neither acidic nor basic. Therefore, option B, which states a pH range of 7, is incorrect. Option C, which states a range of 7-14, includes basic solutions and does not only consist of acidic solutions. Therefore, it is also incorrect. Option D states that none of the above options are correct, but since option A is the correct answer, this statement is also incorrect.
