Applicant's summary and conclusion
- Conclusions:
- pH = 0.6 for 1 M solution
pH = 1.3 for 0.1 M solution
This study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability). - Executive summary:
The final pH of solutions in water made from two concentrations of the test substance for a hydrolysis study were measured. The pH was 0.6 for the 1 M solution and 1.3 for the 0.1 M solution.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
