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:
- other: Information from published review article in peer reviewed literature, minor restrictions in design and/or reporting but otherwise adequate for assessment.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- GLP compliance:
- not specified
- Type of method:
- flask method
- Water solubility:
- 191 g/L
- Temp.:
- 20 °C
- pH:
- 2.3
- Remarks on result:
- other: +/- 1 g/L
- Details on results:
- In some cases the PGM concentrations measured by ICP-OES showed a tendency of increasing values at each equilibration time. If the last two vessels varied by less than 15%, the test was deemed satisfactory. If the last two vessels varied by more than 15% then the analysis was repeated with longer equilibration times until the criteria was met.
- Conclusions:
- Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
The water solubility of dipotassium tetrachloroplatinate was reported as 191 g/L at 20°C. - Executive summary:
The water solubility result is taken from a published review article in peer reviewed literature and followed a standard guideline. The result is considered suitable for use as the key study for this endpoint. The water solubility of dipotassium tetrachloroplatinate was reported as 191 g/L at 20°C.
