Storage class8B Non-combustible, corrosive hazardous materials
WGKWGK 1 slightly hazardous to water
Bases and alcoholates should be diluted if necessary by carefully stirring them into water and then neutralized (protective gloves, fume cupboard!) with hydrochloric acid (Cat. No. 100312). Before placing in container D, check the pH with pH universal indicator strips (Cat. No. 109535).

Supplemental Information
Amount-of-substance concentration0.995 - 1.005
Measurement uncertainty+/- 0.003
TraceabilityNIST SRM
The amount-of-substance concentration of this volumetric solution is analyzed by our quality control laboratory of 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 traceable to a primary standard reference material (SRM) from the National Institute of Standards and Technology, Gaithersburg, USA (NIST SRM 84 potassium hydrogen phthalate) by means of volumetric standard potassium hydrogen phthalate (article number 1.02400), certified reference material according to ISO 17034, analyzed by our accredited calibration laboratory of 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 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.
