Applicant's summary and conclusion

Conclusions:

The pH value of a stannous suphate solution was determinate to be

pH-value Concentration (w/w%)
2.3 1.0
1.8 2.5

Executive summary:

The pH-value of a solution of test item in water was measured according to OECD guideline 122 in anon-GLP study. The pH-value of a 1 % (w/w) solution is 2.3 and of a 2.3 % (w/w) solution is 1.8.
