   Measured on a scale from 0 to 14, pH is based on the concentration of hydrogen ions in a solution. In pure water, which is neutral (neither acidic nor basic), the concentration of hydrogen ions corresponds to a pH of 7.0. This marks the midpoint of the pH scale.

   pH Scale. The pH scale, spanning 0 to 14, classifies substances as acidic, basic, or neutral. Acids score less than 7, while bases score above 7. For instance, lemon juice, a strong acid, measures around 2, whereas baking soda, a base, is about 9. Neutral substances, like pure water, register exactly 7.
