Conditions:
Room Temp:
298
$\pu{K}$
Initial ɸ2 (binary solvent):
0.0 - 0.3
Compiler:
Methodology:
Constant temperature bath, and an ultraviolet/visible spectrophotometer. Excess solute and binary solvent equilibrated in a constant temperature vessel. Aliquots of saturated solution withdrawn and concentrations determined spectrometrically at 283 nm. Attainment of equilibrium verified by several repetitive measurements.
Sample Information:
- Purity and chemical source not specified, was recrystallized from aqueousethanol.
- Purity and chemical source not specified in paper.
- Purity and chemical source not specified in paper.
Measurement Errors:
Ambient temperature: T/K: ±0.1 (Compiler).
Mass concentration (m/v) (1): ø2(s): ±0.01. c1: ±3% (relative error; compiler).
