 48 hour  31.111 mg/L  100  3111.1 mg/L
 72 hour  29.873 mg/L 100   2987.3 mg/L

Considering the water solubility for 48 hrs and 72 hrs the mean water solubility was calculated as follows:

Mean water solubility value for 48 hour run sample + 72 hour run sample

=(3111.1+2987.3)/2

=3049.2 mg/L

Conclusions:
The water solubility determination of test item 2-amino-3,5-dimethylbenzene-1-sulfonic acid;CAS No.88-22-2 was done by spectrophotometric method. The water solubility was determine to be 3049.2 mg/L at 25°C.
