other: Mean value of three measurements.
Details on results:
Results: Preliminary test, water solubility: 1-10 g/L
Sample 1, 24 h: water solubility = 39.48 g/L, pH = 6.15
Sample 2, 48 h: water solubility = 42.12 g/L, pH = 6.13
Sample 3, 72 h: water solubility = 40.00 g/L, pH = 6.14
Values 1-3 are used for the calculation of the average of values.
Water solubility = 40.5 g/l
pH = 6.14
Conclusions:
The solubility of the tested substance was 40.5 g/L at 30°C.
