The concentration of this solution was determined by back-titration with copper(II) nitrate (Merck article number 1.02753) standardized by titriplex(III) solution (Merck article number 1.08431) against volumetric standard zinc (Merck article number 1.02409). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.004 (k=2 coverage factor for 95% coverage probility). The certified value is traceable to primary standard NIST SRM 682 (NIST: National Institute of Standards and Technology, USA) by means of volumetric
