Alkalinity & pH Relationships - Veolia Water Te

Alkalinity Testing The P-, M-, and OH-alkalinity tests are all related to these significant pH s. Acid is added until a pH endpoint is achieved allowing the alkalinity components to be measured. M-Alkalinity The M-alkalinity is a measure of the amount of acid it takes to drop the pH to approximately 4.3.


Alkalinity control is correct when t he boiler water contains enough hydroxide to secure the desired benefits without inviting trouble associated with aggressively high concentrations of caustic. The P (Phenolphthalein) alkalinity test provides a sound basis for control of the alkalinity in b oiler water. pH determination is also widely used for
