Methodology:
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.
Sample Information:
- "Chemically pure"
- distilled water plus salt mixture.
Measurement Errors:
Ambient temperature: Not specified.
System Components:
- Heptane, $\ce{ C7H16 }$; [142-82-5] NIST WebBook
- Seawater, $\ce{ H2O }$; [7732-18-5(C)] NIST WebBook
Experimental Data
The solubility of heptane in seawater was reported to be 1.03 × 10-3 g(1)/100 g sln. And the corresponding mole fraction, x1 = 1.9 × 10-6.
