Results and discussion
Water solubility
- Water solubility:
- > 500 g/L
- Temp.:
- 20 °C
- pH:
- 5.9
- Details on results:
- After the stirring period (nominal concentration of 1.0 x 10E3 g/l), undissolved test substance was observed. After addition of an extra amount of additional double distilled water (nominal concentration 0.5 x 10E3 g/l). the test sample was clear and no undissolved test substance was observed. The pH of the aqueous sample was 5.9.
