initial mol 3 (binary solvent):
0.0 - 0.1

Methodology:
Constant temperature bath, calorimetric thermometer, and an ultraviolet/visible spectrophotometer. Excess solute and solvent placed in amber glass bottles and allowed to equilibrate for several days at constant temperature. Attainment of equilibrium verified by repetitive measurements. Aliquots of saturated solutions transferred through a coarse filter into tared volumetric flasks, weighed and diluted with methanol. Concentrations determined spectrophotometrically at 356 nm.
Sample Information:
- Gold Label, 99.9+%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was used as received.
- 99+ mole%, Aldrich Chemical Company.
- 99+%, anhydrous, Aldrich Chemical Company.
Measurement Errors:
Ambient temperature: T/K: ±0.05.
Initial mole fraction of component 3 in binary solvent mix: x3(s): ±0.0001.
Mole fraction - Liquid (1): x1(s): ±1.5% (relative error).
