Details on results:
Comparison of individual test results from tests 1, 2 and 3 indicated that there was no increasing solubility over time and the concentrations of all test solutions do not differ by more than 15%; therefore the mean results from tests 1, 2 and 3 were reported as the water solubility value.

Average of Day 1, 2 and 3 Tests = 1.85 % w/w
Conclusions:
Water solubility of 2-Hydroxyethyliminodi(acetic acid) was determined using flast method with HPLC analysis. The solubility was determined to be 18.61 g/l (1.85 % w/w) at 25 C.
Executive summary:

Water solubility of 2-Hydroxyethyliminodi(acetic acid) was determined using flast method with HPLC analysis. The solubility was determined to be 18.61 g/l (1.85 % w/w) at 25 C.
