Methodology:
The analytical method was used.
- Method A: 10 to 20 mL of (1) and an appropriate amount of fine dry salt were placed into a glass retort in a thermostat and stirred for many hours. Aliquots of the saturated solution were taken by pipette for titration.
- Method B: 15-25 mL of (1) and finely divided salt were equilibrated at 40 °C with intensive stirring for one hour. The flask was then placed into a thermostat (25 or 0 °C) and stirred for two hours. After this, stirring was halted and the flask kept at the given temperature for 17-18 hrs. The saturated solutions were then sampled and titrated.
