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 1% w/v test dispersion was determined with the help of digital pH meter. The mean pH was determined to be 2.04 at 26.4°C.
Executive summary:

The pH of test chemical was determined. The study was performed in accordance with OECD Guideline 122 (Determination of pH, Acidity and Alkalinity). The mean pH of the 1% w/v test dispersion was determined with the help of digital pH meter. The mean pH was determined to be 2.04 at 26.4°C. Thus, test chemical was considered to be acidic in nature.
