Description of key information
Key value for chemical safety assessment
- Water solubility:
- 11.3 g/L
- at the temperature of:
- 20 °C
Additional information
Under the conditions of this test (under exclusion of CO2 and O2, under inert argon gas; flask method; loadings of 100.001 and 100.002 g/L in vessel A and B, respectively), a solubility equilibrium was reached during the three days of testing. The mean amount of dissolved V from day 1 until day 3 at 20.0 ± 1.0 °C is 4.571 ± 0.217 g/L (determined as dissolved V, separated by filtration from undissolved test item). This corresponds to a water solubility of dissolved ammonium sodium vanadium oxide of 11.34 ± 0.54 g/L, calculated based on a vanadium content of 40.3 %. Solution pH in samples containing the test item and in method blanks ranged from 6.4 to 6.6 and from 6.5 to 6.8, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
