Applicant's summary and conclusion

Conclusions:
The pH determination of test chemical was done as per the test guideline OECD 122. The mean pH of the test dispersion was determined with the help of digital pH meter. The mean pH value was determined to be 4.91 at 28 °C, which indicated that the chemical was acidic
