Notes
1. The terms Alkalinity-p, p-Value and Alkalinity to pH 8.2 are identical.
2. For accurate test results exactly 10 ml of water sample must be taken for the test.
3. Thismethod was developed from a volumetric procedure for the determination of
Alkalinity-p. Due to undefined conditions, the deviations from the standardisedmethod
may be greater.
4. Conversion table:

6. By determining Alkalinity-p and Alkalinity-m it is possible to classifythe alkalinity as
Hydroxide, Carbonate and Hydrogencarbonate.
The following differentiation is only valid if:
a) no other alkalis are present and
b) Hydroxide und Hydrogen are not present in the same water sample.
If condition b) is not fulfilled pleaseget additional information from ”Deutsche
Einheitsverfahren zur Wasser-,Abwasser- und Schlammuntersuchung, D 8”.
Case1: Alkalinity-p = 0
Hydrogen carbonate = m
Carbonate = 0
Hydroxide = 0
Case2: Alkalinity-p > 0 and Alkalinity-m > 2p
Hydrogen carbonate = m – 2p
Carbonate = 2p
Hydroxide = 0
Case3: Alkalinity-p > 0 and Alkalinity-m < 2p
Hydrogen carbonate = 0
Carbonate = 2m – 2p
Hydroxide = 2p – m
Reagent Form of reagent/Quantity Order-No.
