Determination method: Argentometric titration.
The content of this solution was determined with silver nitrate standard solution (article number 1.09081) standardized against volumetric standard sodium chloride (article number 1.02406). The expanded measurement uncertainty is ± 0.4 % (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 999b (NIST: National Institute of Standards and Technology USA) by means of volumetric standard sodium chloride measured in the accredited calibration laboratory of Merck KGaA Darmstadt Germany in accordance to DIN EN ISO/IEC 17025.
