Applicant's summary and conclusion

Conclusions:
pH of 1% w/v aqueous solution of the test substance was determined to be 6.6 at 25 °C.
Executive summary:

The pH determination of test substance was performed as per the test guideline OECD 122. The pH of the test solution was determined with the help of pH meter which was determined to be 6.6 at 25 °C indicating that the substance is acidic in nature.
