Results and discussion

pH value

pH value:

4.96

Temp.:

25.1 °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 10g/L (1% (w/v)) Dichlorophenacyl Chloride suspension was 4.96 at 25.1 °C.
