| Concentration after dilution to 1 liter: c(C₁₀H₁₄N₂Na₂O₈ ∙ 2 H₂O) = 0.1 mol/l | |
| Amount-of-substance concentration | 0.1000 mol/l |
| The concentration of this solution was determined with volumetric standard zinc (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 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, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025. | |
