Results and discussion

pH value
pH value:
5.02
Temp.:
24 °C
Concentration:
10 g/L
Remarks on result:
other: emulsion

Any other information on results incl. tables

As the water solubility of test item is less than 1% w/v so an emulsion was resulted.

After stirring the two phases were allowed to separate for 5 minutes. The pH was measured from the aqueous phase.

Applicant's summary and conclusion

Conclusions:
The measured pH of 10 g/L Difluoro-Bromo-Benzene (CAS No. 348-57-2) emulsion was 5.02 at 24.7 °C.
