Results and discussion

pH value
pH value:
2.6
Temp.:
24.6 °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 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 10 g/L 2,3-Dichlorobenzoic Acid (CAS No. 50-45-3) suspension was 2.60 at 24.6 °C.
