McLaughlin, E.; Scott, R. L.; J. Phys. Chem. 1954, 76, 5276-5279.
Variables:
Ambient temperature: 298 K, 308 and 318 K
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath, a precision thermometer and uv/visible spectrometer.
Mixtures of known concentrations sealed in glass ampoules and pre-equilibrated for four days at an elevated temperature. Saturated solutions were then transferred to a special solubility flask and equilibrated for three days at desired temperature. Aliquots removed, diluted ten-fold with solvent and concentrations determined spectrophotometrically at 270 nm.
Source and Purity of Materials:
- White Label, Eastman Kodak Company, Rochester, New York, USA, was recrystallized five times from ethanol to give a melting point of 101°C.
- Purity not specified, Minnesota Mining & Manufacturing Company, USA, was distilled shortly before use.
Estimated Errors:
Ambient temperature: T/K: precision ±0.02. x1: ±2% (relative error; compiler).
Experimental Values:
| T (°C) | x1 | x2 |
|---|---|---|
| 25.0 | 2.92 x 10-2 | 9.708 x 10-1 |
| 35.0 | 4.89 x 10-2 | 9.511 x 10-1 |
| 45.0 | 7.22 x 10-2 | 9.278 x 10-1 |
