              Inorganic acids and anhydrides thereof should first be diluted or hydrolyzed by stirring carefully into ice water and then neutralized (protective gloves, fume cupboard!) with sodium hydroxide solution (Cat. No. 105587). Before filling into container D, check the pH with pH universal indicator strips (Cat. No. 109535). Fuming sulfuric acid should be carefully stirred dropwise into 40 % sulfuric acid (Cat. No. 109286). Ensure that plenty of ice is available for cooling! When sufficiently cool, treat the highly concentrated sulfuric acid as described above. Analogous to this procedure, other anhydrides can be converted into their corresponding acids. Acid gases (e.g. hydrogen halide, chlorine, phosgene, sulfur dioxide) can be introduced into dilute sodium hydroxide solution and after neutralization disposed of in container D.

              Accreditation: This volumetric solution is certified according to DIN EN ISO/IEC 17025. KGaA, Darmstadt, Germany is accredited as calibration laboratory D-K-15185-01-00 for amount-of-substance concentrations in volumetric solutions according to DIN EN ISO/IEC 17025 by DAkkS (Deutsche Akkreditierungsstelle). The accreditation certificate can be found at www.sigmaaldrich.com/ISO17025.
              The concentration is determined by volumetric titration and refers to 20°C.
              The certified value of this volumetric solution was determined with sodium thiosulfate standard solution (article number 1.09147). The sodium thiosulfate standard solution is standardized and traceable to a primary standard from the National Institute of Standards and Technology, Gaithersburg, USA (NIST SRM 136 potassium dichromate) by means of volumetric standard potassium iodate (article number 1.02404). This volumetric standard is certified by the accredited calibration laboratory of KGaA, Darmstadt, Germany according to DIN EN ISO 17025. The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%. All measurements are carried out in the calibration laboratory D-K-15185-01-00 of KGaA, Darmstadt, Germany.
              Note: The titer is a correction factor to correct for variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. For correct titration results it is recommended to determine a titer with the laboratory specific equipment and under laboratory specific conditions directly after opening a new bottle and at regular time intervals.
