USP HS Code 2832 30 00 Physicochemical Information Density 1.01 g/cm3 (20 °C) pH value 9 - 10 (H₂O, 20 °C) Safety Information according to GHS Storage class 10 - 13 Other liquids and solids WGK NWG not water endangering Disposal 28 Aqueous solutions: Container D. Storage and Shipping Information Storage Store at +15°C to +25°C. Transport Information Declaration (railroad and road) ADR, RID Kein Gefahrgut Declaration (transport by air) IATA-DGR No Dangerous Good Declaration (transport by sea) IMDG-Code No Dangerous Good Specifications Volumetric solution in accordance to the chapter reagents of the Pharmacopoeia (Ph Eur, USP). Amount-of-substance concentration 0.1000 mol/l The concentration of this volumetric solution was determined with volumetric standard potassium iodate (article number 1.02404). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.003 (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.
