Alkalinity P

Alkalinity
Alkalinity P and Alkalinity M (Total Alkalinity) are important tests in boiler water treatment control where the pH of water is over 8.5. It is usually reported in mg/l as Calcium Carbonate (CaCO3).
Alkalinity P is the alkalinity of the water to pH 8.3 and uses a phenolphalein based indicator. The reading obtained represents the alkalinity due to hydroxides plus half the alkalinity due to carbonates.
