水溶液:第D类.规格 规格 Concentration after dilution to 1 liter: c(C₂H₂O₄) = 0.005 mol/l Amount-of-substance concentration 0.005000 mol/l The concentration of this solution was determined with potassium permanganate solution (manufacture by Merck article number 1.09930) standardized against volumetric standard di-sodium oxalate (Merck article number 1.02407). The expanded measurement uncertainty is ± 0.004 (k=2 coverage factor for 95% coverage probility). The certified value is traceable to primary standard NIST SRM 8040 (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard di-sodium oxalate measured in the accredited calibration laboratory of Merck KGaA in accordance to DIN EN ISO/IEC 17025
