- Remarks on result:
- other: Mean value of three measurements. Temperature was indicated as "room temperature" and is assumed to be 20 °C.
- Details on results:
- Results: Preliminary test, water solubility: 1-10 g/l
Sample 1, 24 h: water solubility = 28.44 g/l, pH = 11.60
Sample 2, 48 h: water solubility = 29.46 g/l, pH = 11.60
Sample 3, 72 h: water solubility = 29.20 g/l, pH = 11.70
Values 1-3 are used for the calculation of the average of values. - Conclusions:
- The water solubility of calcium dibenzoate is determined using the flask method to 29.0 g/L at room temperature with a pH of 11.6.
