水溶液:第D类.规格 规格 Concentration after dilution to 1 liter: c(Na₂S₂O₃) = 0.1 mol/l Amount-of-substance concentration 0.1000 mol/l The concentration of this solution was determined with volumetric standard potassium iodate (Merck article number 1.02404). 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 136f (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard potassium iodate, measured in the accredited calibration laboratory of Merck KGaA in accordance to DIN EN ISO/IEC 17025.
