Results and discussion
Water solubility
- Water solubility:
- 0.005 g/L
- Temp.:
- 25 °C
- pH:
- 6.04
- Details on results:
- Result of the first run:
The calculated mean solubility for the first run was 0.004116 g/l (4.116 mg/l). The standard deviation was 0.0000796 g/l (0.0796 mg/l).
The temperature of the circulated solution was 25 °C.
Result of the second run:
The calculated mean solubility for the second run was 0.00494 g/l (4.94 mg/l). The standard deviation was 0.0001526 g/l (0.1526 mg/l).
The temperature of the circulated solution was 24.9 °C.
The average value of solubility calculated from the two runs is 0.004528 g/l (4.528 mg/l). The standard deviation was 0.0005827 g/l (0.5827 mg/l).
