(39423-51-3) 60-100% - Key result
- Water solubility:
- 562 g/L
- Temp.:
- 20 °C
- pH:
- 12.7
- Details on results:
- Preliminary test:
A water solubility of 361.3 g/L was estimated in the preliminary test.
Formal solubility test:
The mean value for the water solubility determined in the formal solubility test using the shake flask method, is 5.62 E+02 g/L. Consequently, the test material is considered very soluble (> 10000 mg/L)
The pH of 12.7 is an average of 12.68, 12.72 and 12.69 as determined in the three flasks. - Conclusions:
- The water solubility of the substance is 562 g/L at 20 °C (pH 12.7)
Reference
Description of key information
