水溶液:第D类.规格 规格 Concentration after dilution to 1 liter: (NH₄SCN) = 0.1 mol/l Amount-of-substance concentration 0.1000 mol/l Determination method: Argentometric titration.
The concentration of this solution was determined with silver nitrate standard solution (Merck article number 1.09081) standardized against volumetric standard sodium chloride (Merck article number 1.02406). 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 999b (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard sodium chloride, measured in the accred
