Hazard Statement(s)H226: Horľavá kvapalina a pary.
H314: Spôsobuje vážne poleptanie kože a poškodenie očí.
Precautionary Statement(s)P210: Uchovávajte mimo dosahu tepla, horúcich povrchov, iskier, otvoreného ohňa a iných zdrojov zapálenia. Nefajčite.
P233: Nádobu uchovávajte tesne uzavretú.
P240: Uzemnite a upevnite nádobu a plniace zariadenie.
P280: Použite ochranné rukavice/ ochranný odev/ ochranu očí/ ochranu tváre/ ochranu sluchu.
P303 + P361 + P353: PRI KONTAKTE S POKOŽKOU (alebo vlasmi): Vyzlečte všetky kontaminované časti odevu. Pokožku ihneď opláchnite vodou.
P305 + P351 + P338: PO ZASIAHNUTÍ OČÍ: Niekoľko minút ich opatrne vyplachujte vodou. Ak používate kontaktné šošovky a je to možné, odstráňte ich. Pokračujte vo vyplachovaní.

Anorganické kyseliny a ich anhydridy najprv zrieďte alebo hydrolizujte opatrným primiešaním do ľadovej vody a potom neutralizujte (rukavice, komora s odsávaním) hydroxidom sodným (kat. č. 105587). Pred vyliatím do nádoby D skontrolujte pH pomocou indikátorových prúžkov pH-Universal (kat č. 109535). Dymivú kyselinu sírovú opatrne primiešajte po kvapkách do 40 % kyseliny sírovej (kat. č. 109286). Majte po ruke veľké množstvo ľadu na chladenie. Po dostatočnom ochladení upravte vysokokoncentrovanú kyselinu sírovú tak, ako je uvedené vyššie. Obdobne anhydridy je možné premeniť na príslušné kyseliny. Kyslé plyny (napr. halidy vodíka, chlór, fosgén, oxid siričitý) je možné prebublať cez zriedený roztok hydroxidu sodného a po neutralizácii zneškodniť v nádobe 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.
