Introduction
The determination was carried out using Method A6 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
Method
Water solubility at a pH 4 to 6, ambient pH (6 to 6.3) and pH 8 to 10 was assessed using the flask shake method.
Results and Conclusion
The water solubility of Tribasic Copper Sulphate at 20 ± 0.5 °C was determined to be:
At pH 4 to 6 = 0.5 g/l
At pH 6 to 6.3 (ambient pH) = < 0.0032 g/l
At pH 8 to 10 = <0.000255 g/l
Reference
Results from the Preliminary Tests
Preliminary test result at pH range 4 to 6
The preliminary estimate of water solubility was 0.491g/l.
Preliminary test result at ambient pH
