Details on results:
Results: Preliminary test, water solubility: 1-10 g/L
Sample 1, 24 h: water solubility = 1.22 g/L, pH = 3.41
Sample 2, 48 h: water solubility = 1.25 g/L, pH = 3.39
Sample 3, 72 h: water solubility = 1.29 g/L, pH = 3.33
Values 1-3 are used for the calculation of the average of values.
Water solubility = 1.25 g/l
pH = 3.38
Conclusions:
The solubility of m-toluic acid was 1.25 g/L at 30°C under these experimental conditions.
