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 was determine to be 4.49 at 25 °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 4.49 at 25°C. Thus, test chemical was considered to be acidic in nature.
