Results and discussion

Water solubility

Water solubility:

ca. 0.415 mg/L

Temp.:

20 °C

pH:

>= 5.5 - <= 6

Details on results:

The water solubility at 20°C was determined as 0.389 – 0.462 mg/L (mean 0.415 mg/L), and agitation time had no bearing on the individual results. The pH of the solutions was slightly acid at between 5.5 and 6.
