Variables:
Room Temp: 299.7 - 341.3 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer. Solubilities were measured using a dynamic method. Mixtures of known concentrations were sealed in thick-walled glass tubes and placed in a constant temperature to equilibrate with gentle rotation to thoroughly mix contents. Bath temperature was slowly increased and solubility visually determined by noting the temperature at which the last trace of solid solute disappeared. Measurements repeated several times to verify results.
Source and Purity of Materials:
- Purity not specified, Eastman Kodak Company, Rochester, New York, USA, was recrystallized three times from alcohol.
- Purity not specified, Eastman Kodak Company, was used as received.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x1: ±0.002 (compiler).
Components:
- Biphenyl, $\ce{ C12H10 }$; [92-52-4] NIST WebBook
- Heptane, $\ce{ C7H16 }$; [142-82-5] NIST WebBook
