Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Justification for type of information:
As the substance is not possible to isolate from water without possible chemical changes, finding an absolute solublity in water is not possible
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 105 (Water Solubility)
Version / remarks:
Solublity measured at different pH levels
Principles of method if other than guideline:
The solublity was measured by drying and then re-dissolving in different proportions in water and at different pH
GLP compliance:
no
Type of method:
flask method
Water solubility:
ca. 500 g/L
Conc. based on:
test mat.
Loading of aqueous phase:
500 g/L
Temp.:
20 °C
pH:
ca. 1.1
Remarks on result:
other: Supplied as up to 40% in water. Attempts to remove water led to colour change, suggesting change in oxidation state
Water solubility:
< 100 g/L
Conc. based on:
test mat.
Loading of aqueous phase:
100 g/L
Temp.:
20 °C
pH:
ca. 4
Remarks on result:
other: At higher pH, solublity is greatly reduced

The substance is mannufactered and supplied in solution at up to 40% (400 g/l w/w) and has pH 1.1

Attemptes to remove water led to colour change suggesting changes in oxidation state of the vanadium

A nominal 500 g/l is used for the CSR

Conclusions:
The substance is mannufactered and supplied in solution at up to 40% (400 g/l w/w).
Attemptes to remove water led to colour change suggesting changes in oxidation state of the vanadium
A nominal 500 g/l is used for the CSR

Description of key information

Attemptes to remove water led to colour change suggesting changes in oxidation state of the vanadium

A nominal 500 g/l is used for the CSR

Key value for chemical safety assessment

Water solubility:
500 g/L
at the temperature of:
