Is pH an indicator of water quality?
pH is a measure of how acidic/basic water is. … Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically. pH is reported in “logarithmic units”.
