| Concentration after dilution to 1 liter: c(KMnO₄) = 0.02 mol/l | |
| Amount-of-substance concentration | 0.02000 mol/l |
| The concentration of this solution was determined with volumetric standard di-sodium oxalate (article number 1.02407). 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 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, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025. | |
