    Amount-of-substance concentration0.5000 mol/l
    The concentration of this volumetric solution was determined with volumetric standard potassium hydrogen phthalate (Merck article number 1.02400). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.004 (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 84L (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard potassium hydrogen phthalate, measured in the accredited calibration laboratory of Merck KGaA in accordance to DIN EN ISO/IEC 17025.
