Specifications
Concentration β (CrO₄²⁻)	990 - 1010 mg/l
Determination method: Iodometric titration. The content of this solution was determined with sodium thiosulfate standard solution (article number 1.09147) standardized against volumetric standard potassium iodate (article number 1.02404). The expanded measurement uncertainty is ± 0.4 % (k=2 coverage factor for 95% coverage probability). 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, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025.
