Results and discussion

pH value
pH value:
10.1
Temp.:
23.4 °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 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 Imidazole Ethanol (CAS No. 24155-42-8) suspension was 10.10 at 23.4 °C.
