Acid solutions have a pH between 0 (most acidic) and 7.0 (less acidic).
Explanation:
The pH (Hydrogen potential) of a solution indicates its molecular concentration of Hydrogen ions.
The pH scale measures the acidity or basicity (alkalinity) of a solution. It goes from 0 to 14 and is balanced at 7.0 (neutral); everything below 7.0 is acidic, and everything above it is basic/alkaline.
The lower the pH, the higher concentration of hydrogen ions.
