Alkalinity - Water Quality Parameter Overview and Products ...

Alkalinity is a measure of the capacity of water to neutralize acids. This is known as the buffering capacity of water, or the ability of water to resist a change in pH when acid is added. Alkalinity in water (with a pH of 7.0 or higher) is caused primarily by the presence of dissolved acid-neutralizing substances (alkali).
