pH: Definition and measurement units. pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
