What Exactly Is pH? | Treatment Plant Operator

A base (or alkali) substance is one that will accept protons, thereby neutralizing the acid. An example of an alkali is hydroxyl (OH-), which when combined with the ,acidic, hydronium ion (H3O+) neutralizes, forming two molecules of water: OH- + H3O+ → 2H2O. Raw ,wastewater, generally has a pH near neutral (7.0), although it may vary between 6 and 8.
