Original Measurements
McLuaghlin, E.; Messer, C. E.; J. Chem. Soc.; Sect. A 1966, 1106-1110.
Variables:
Ambient temperature: Temperature
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer. Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by noting the temperature at which the last trace of solid solute disappeared.
Source and Purity of Materials:
- Purity not given, Gesellschaft fur Teerverwertung, passed over alumina column, recrystallized and sublimed.
- Purity not given, Imperial Smelting, Ltd, Avonmouth, Bristol, was dried over anhydrous calcium sulfate.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x1: ±0.0003.
