solution or dispersion in water was

determined with a pH

measurement interface equipped

with an appropriate electrode

system.

Applicant's summary and conclusion

Conclusions:
The pH of 1% w/v solution of the test chemical was determined to be 11.25 at 29 °C, which indicates that the test chemical was basic in nature.
Executive summary:

The pH determination of test chemical was done as per the test guideline OECD 122. The mean pH of the test solution was determined with the help of digital pH meter. The pH of 1% w/v solution of the test chemical was determined to be 11.25 at 29 °C, which indicates that the test chemical was basic in nature.
