Method/Apparatus/Procedure:
Saturated solutions were prepared by shaking in a thermostat and were analyzed by means of an interferometer. The instrument used was a combination liquid and gas interferometer made by Zeiss.
Source and Purity of Materials:
- Baker's CP analyzed grade; distilled; BP = $\pu{110.74 \pm 0.02 ^{\circ}C}$
- Distilled.
Estimated Errors:
Mass concentration (m/v) (1): 2.0% (from values of duplicate determinations)
Components:
- Toluene, $\ce{ C7H8 }$; [108-88-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of toluene in water at 30°C was reported to be 0.57 g(1)/kg (2) and 0.0062 mol (1)/kg (2).
The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.057 g(1)/100 g solution and 1.12 × 10-4.
