Any other information on results incl. tables
The results quoted in the report are in mg/mL. Calculation of the results as g/L (mg/ml x 1 000/1 000) gave the same value in g/L.
The pH values of the approximately 90 % saturated and half-saturated solutions were measured as 3.07 and 3.22 respectively at 20 °C.
Applicant's summary and conclusion
