    Concentration after dilution to 0.5 liter: c(CH₃COOH) = 1 mol/l
    Amount-of-substance concentration1.000 mol/l
    The concentration of this solution was determined with sodium hydroxide standard solution (Merck article number 1.09137) standardized by hydrochloric acid 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 ± 0.004 (k=2 coverage factor for 95% coverage probility). 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 accre
