Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- A saturated solution of the test item in water was prepared. A volume of this solution was then removed and diluted with an aliquot of water before analysis by ICP-OES. The PGM content of the solution is back-calculated from the ICP-OES result.
- GLP compliance:
- not specified
- Type of method:
- other: PGM content of the saturated solution has been calculated from the analysis of diluted sample solution by ICP-OES.
- Water solubility:
- 696 other: g Rh (III) Chloridhydrate/ kg solution
- Temp.:
- 20 °C
- Remarks on result:
- other: pH; not reported, temperature; room temperature, nominally 20°C
- Details on results:
- As a determination of the solution density has not been performed the results are in g per kg solution not g/L.
- Conclusions:
- The solubility of Rh (III) Chloridhydrate has been reported as 696 g Rh (III) Chloridhydrate/Kg solution.
- Executive summary:
This is a non-GLP study that does not follow a standard guideline but does follow a reliable test method. It is considered to be suitable for assessment as the key study for this endpoint. The solubility of Rh (III) Chloridhydrate has been reported as 696 g Rh (III) Chloridhydrate/Kg solution.

Key value for chemical safety assessment
Additional information
Winde (2011) is a non-GLP study that does not follow a standard guideline but does follow a reliable test method. It is considered to be suitable for assessment as the key study for this endpoint. The solubility of rhodium trichloride (hydrate) is reported as 696 g Rh trichloride (hydrate)/Kg solution.
