              Asam-asam anorganik dan anhidrida pertama-tama harus diencerkan atau dihidrolisa dengan diaduk hati-hati ke dalam air es, kemudian dinetralisir (sarung tangan pelindung, lemari uap!) dengan larutan natrium hidroksida (Kat. No. 105587). Sebelum dimasukkan ke dalam ke wadah D, periksa derajat keasaman (pH) dengan indikator pH universal (Kat. No. 109535). Asam sulfat yang mudah menguap harus diaduk dan diteteskan secara hati-hati ke dalam 40 % asam sulfat (Kat. No. 109286). Pastikan gunakan es secukupnya untuk pendinginan! Jika sudah cukup dingin, perlakukan asam sulfat pekat seperti yang telah dijelaskan sebelumnya. Seiring dengan prosedur ini, anhydrida yang lain dapat dikonversikan ke asam-asam turunannya. Gas-gas asam (hidrogen bromida, hidrogen klorida dan hidrogen iodida, klorin, fosgen, belerang dioksida) harus dibuihkan ke dalam larutan natrium hidroksida encer dan setelah dinetralisir, tampung ke dalam wadah D.

              The stated batch and specification values for the amount of substance concentration are valid at the time of bottling.
              The amount-of-substance concentration of this volumetric solution is analyzed by our quality control laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025.
              The concentration is determined by volumetric titration and refers to 20°C.
              The amount-of-substance concentration of this volumetric solution is determined with standardized sodium thiosulfate solution (article number 1.09147). The sodium thiosulfate solution is standardized and traceable to a primary standard reference material (SRM) 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), certified reference material according to ISO 17034, analyzed by our accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025. The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%.
              Note: The concentration of this volumetric solution decreases over time, due to its chemical properties. If high accuracy is expected, the titer, being a corrective factor that compensates for this effect as well as variations of equipment, personal handling, temperature and other laboratory conditions, must be determined directly after opening a new bottle and should be verified at regular intervals.
