Approximate Values of Activity Coefficients from LLE Data for a Partially Miscible Mixture
When n-octanol and water are mixed, two liquid phases form. The water-rich phase is essentially pure water containing only 0.7 \times 10^{-4} mole fraction n-octanol, while the octanol-rich phase contains approximately 0.26 mole fraction water. Estimate approximately the activity coefficient of n-octanol in water and water in n-octanol.
