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:
- no guideline followed
- Principles of method if other than guideline:
- A simplified water solubility test was followed. A known quantity of the test item was weighed into a conical flask and 20 mL of water was added. The flasks were stoppered and agitated in an orbital shaker water bath. After 24 hours, flasks are removed and allowed to equilibrate for 24 hours prior to filtering with a 0.1 μm cellulose nitrate membrane filter. ICP-OES was used to determine the concentration of the PGM in the resulting solution.
- GLP compliance:
- not specified
- Type of method:
- flask method
- Water solubility:
- > 10 g/L
- pH:
- 1.3
- Remarks on result:
- other: Temperature not reported
- Details on results:
- The amount of test material used was sufficient to produce a saturated solution for substances with water solubility below 10 g/L. For substance that were soluble at this level, >10 g/L was reported as the limit of solubility.
- Conclusions:
- The water solubility of diammonium hexachloropalladate has been determined to be >10 g/L of solution using a simplified water solubility test.
- Executive summary:
Information from a published review article in peer reviewed literature, minor restrictions in design and/or reporting but otherwise adequate for assessment. The water solubility of diammonium hexachloropalladate has been determined to be >10 g/L of solution using a simplified water solubility test.
Reference
Water solubility of substance using the simplified test;
| Substance | CAS Number | Water solubility (g/L) | pH |
| Diammonium hexachloropalladate | 19168 -23 -1 | >10 | 1.3 |
Description of key information
The water solubility of diammonium hexachloropalladate is >10 g/L.
Key value for chemical safety assessment
- Water solubility:
- 10 g/L
- at the temperature of:
- 20 °C
Additional information
A non-GLP, modified guideline method was used to determine the water solubility of diammonium hexachloropalladate (Gregory 2014). The study is available as a published report and is considered to be suitable for use as the key study for this endpoint. The water solubility of diammonium hexachloropalladate is >10 g/L.
