Results and discussion
pH value
- pH value:
- 2.98
- Temp.:
- 22.8 °C
- Concentration:
- 10 g/L
- Remarks on result:
- other: suspension
Any other information on results incl. tables
As the water solubility of test item is less than 1 w/v % (10 g/L) so a suspension was resulted.
After stirring the solid particles were allowed to settle for 5 minutes. The pH was measured from the supernatant of the suspension.
Applicant's summary and conclusion
- Conclusions:
- The measured pH of 1 w/v % (10 g/L) 4-nitrophenylacetic-acid (CAS No. 104-03-0) suspension was 2.98 at 22.8 °C.
