    Amount-of-substance concentration0.1000 mol/l
    The concentration of this volumetric solution was determined with titriplex-III standard solution (Merck article number 1.08431) standardized against volumetric standard zinc (Merck article number 1.02409). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.003 (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 682 (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard zinc, measured in the accredited calibration laboratory of Merck KGaA in accordance to DIN E
