Applicant's summary and conclusion

Conclusions:

The pH of 1% w/v aqueous solution of the test chemical was determined to be 6.3 at 30 °C

Executive summary:

The pH determination of test chemical was done following OECD Guideline 122 (Determination of pH, Acidity and Alkalinity). pH of 1% w/v aqueous solution was measured with the help of pH meter and it was observed to be 6.3 at 30°C. Thus, based on this pH, test chemical is considered to be acidic in nature.
