- Preliminary test
The preliminary visual experiments showed that the water solubility of the test item is > 10 mg/L. According to the preliminary visual estimation in the main test the water solubility was determined by the flask method.
Flask method
As the preliminary estimated water solubility of the test item was very high the performance of the main test with fivefold excess of the test item was not feasible. After the equilibration time no precipitate was observed in the flasks. As the test item was dissolved completely no further analytical determination was performed. - Conclusions:
- The water solubility of the test item Tetraamminepalladium(II)acetate at a temperature of 20 °C was determined to be >1008 g/L.
- Executive summary:
The water solubility of the test item Tetraaminepalladium(II)acetate was determined in a GLP study according to OECD 105 and EC A.6 guidelines (Winkler 2016). The water solubility of Tetraamminepalladium(II)acetate at a temperature of 20 °C was determined to be >1008 g/L.
