    Volumetric solution in accordance to the chapter reagents of the Pharmacopoeia (JP).
    Amount-of-substance concentration0.02000 mol/l
    The concentration of this volumetric solution was determined with hydrochloric acid standard solution (Merck article number 1.09060) standardized against volumetric standard Tris(hydroxymethyl)aminomethane (Merck article number 1.02408). 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 723e (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard Tris(hydroxmethyl)aminomethane, measured in the accredited c
