Results and discussion

pH value
pH value:
2.94
Temp.:
24.3 °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 for an hour 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) Ethyl-cyclopentanedione (CAS No. 823-36-9) suspension was 2.94 at 24.3 °C.
