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 1 h. The flask was then placed into a thermostat (25 or 0 °C) and stirred for 2 h. After this, stirring was halted and the flask kept at the given temperature for 17-18 h. The saturated solutions were then sampled and titrated. The International Union of Pure and Applied Chemistry Walden, P.; Z. Phys.
