Conditions:

Room Temp: 299 $\pu{K}$

Compiler:

W.E. Acree, Jr.

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 course filter into tared volumetric flasks, weighed and diluted with methanol. Concentrations determined spectrophotometrically at 372 nm.

Sample Information:

1. 99%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, recrystallized three times from absolute ethanol.
2. Puriss, 99+%, Fluka Chemical Corporation, Ronkonkoma, New York, USA, was stored over molecular sieves and distilled before use.

Measurement Errors:

Ambient temperature: T/K: ±0.05. x₁: ±1.5% (relative error).
