Avoid exposure - obtain special instructions before use.In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible).规格 规格 Concentration after dilution to 1 liter: c(Br₂) = 0.05 mol/l Amount-of-substance concentration 0.05000 mol/l The concentration of this solution was determined with sodium thiosulfate standard solution (Merck article number 1.09147) standardized against 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 a
