pH Scale

Though pH does not have an upper or lower bound, the pH scale usually functions between 0 to 14, with 7 being neutral. A pH above 7 indicates a basic or alkaline substance, and those below 7 indicate acidity. The pH scale is logarithmic, meaning that with each individual number change on the scale, there is a ten-fold change in acidity or alkalinity.

Acid and base indicators are sensitive to the change of pH, or more specifically, to the change in the concentration of hydrogen ions, H+, in solution. A pH scale measures the amount of H+, and the higher the pH value, the smaller the amount of H+ in the solution.
