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:
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

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

Key value for chemical safety assessment

Water solubility:
500 g/L
at the temperature of:
20 °C
