The concentration (g/l) of test material in the sample solutions

Sample number	Time shaken at ~ 30°C (hours)	Time equilibrated at 20°C (hours)	Concentration (g/l)	Solution pH
1 2 3	24 48 72	24 24 24	1.93 x 10^-3 2.46 x 10^-3 1.48 x 10^-3	5.05 5.41 5.55

Mean concentration: 1.96 x 10^-3 g/l at 20.0 ± 0.5°C

Range: 1.48 x 10^-3 to 2.46 x 10^-3 g/l

Conclusions:

The water solubility of APAN has been determined to be 1.96 x 10-3 g/l of solution at 20.0 ± 0.5 °C.
