Applicant's summary and conclusion

Conclusions:
The pH determination of test substance was done as per the test guideline OECD 122. The pH of the test solution was determined with the help of pH meter. The pH was determine to be 5.68 at 30°C.Hence the substance is acidic in nature.
Executive summary:

The pH determination of test substance was done as per the test guideline OECD 122. The pH of the test solution was determined with the help of pH meter. The pH was determine to be 5.68 at 30°C.Hence the substance is acidic in nature.
