Method/Apparatus/Procedure:
A saturated solution was prepared by vigorously stirring hydrocarbon (1) in seawater (2) for 10-12 hrs. in a flask placed in a temperature controlled bath. A sample of solution was then transferred to a closed flask with head space volume equal to solution volume. Hydrocarbon concentration in the head space was determined by gas chromatography and the corresponding solution concentration calculated.
Source and Purity of Materials:
- "Chemically pure"
- distilled water plus salt mixture.
Estimated Errors:
Ambient temperature: Not specified.
Components:
- Octane, $\ce{ C8H18 }$; [111-65-9] NIST WebBook
- Seawater, $\ce{ H2O }$; [7732-18-5(C)] NIST WebBook
Experimental Data
The solubility of octane in seawater was reported to be 2.5 × 10-4 g(1)/100 g sln, and the corresponding mole fraction, x1 = 4.0 × 10-7.
