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

=(3608.03+4623.12 )/2

=4115.575 mg/l

Conclusions:
The solubility of (disulfo copper phthalocyanine amine salt of 1328-51-4 )in water was determined to be 4115.575 mg/l at 28°C.
