Water quality - Determination of total alkalinity in sea water using high precision potentiometric titration

ISO 22719:2008 specifies an open-cell potentiometric titration determination of total alkalinity in sea water. The results are expressed in moles per kilogram of sea water. The method is suitable for assaying oceanic levels of total alkalinity (2 000 µmol kg^–1 to 2 500 µmol kg^–1) for normal sea water of practical salinity ranging from 30 to 40.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
