Method/Apparatus/Procedure:
A mixture of (1) and (2) was equilibrated for at least 12 hrs in a 200 mL Teflon stoppered vessel with gentle shaking. The solution was allowed to settle for 6 hrs and the aqueous phase was tested (Tyndall effect). Both phases were analysed by the gas chromatographic technique of internal standardization. The (1) in the aqueous phase was extracted into 5 mL of heptane and the extract analysed by GLC. The instrument was a Hewlett-Packard model equipped with a flame ionization detector.

Estimated Errors:
Ambient temperature: ±0.1 K
Mass concentration (m/v) (1): ±1 mg(1) dm-3 sln
Components:
- 2-Methylpentane, $\ce{ C6H14 }$; [107-83-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of 2-methylpentane in water at 25°C was reported to be 14.2 mg(1) dm-3 sln.
With the assumption of a solution density of 1.00 g cm-3, the corresponding mass percent is 0.00142 g(1)/100 g sln and the corresponding mole fraction, x1, is 3.0 × 10-6 (compiler).
