              Acizii anorganici si anhidridele lor trebuie, mai Intai diluate sau hidrolizate prin amestecare cu grija in apa cu gheata, apoi neutralizate (manuşi de protectie, etuva) cu solutie de hidroxid de sodiu (Cod Merck 105587). Inainte de plasarea in container-ul D, verificati pH-ul cu strip-uri indicatoare de pH, universal (Cod Merck 109535). Acidul sulfuric fumans trebuie amestecat cu grija, picatura cu picatura, in acid sulfuric 40 %, (Cod Merck 109286) sub agitare. Asigurati-va ca aveti la indemana multa gheata penru racire. Cand s-a racit suficient, tratati acidul sulfuric foarte concentrat conform metodei descrise mai sus. Conform acestei proceduri, si alte anhidride pot fi convertite in acizii corespunzatori.Gazele acide (acid clorhidric, clor, fosgen, dioxid de sulf) pot fi barbotate in solutie diluata de hidroxid de sodiu si, dupa neutralizare, introduse in container-ul 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.
