The concentration of tetrachlorocrudene in trout in Lake Gouda averages 0.2 ppm; in the lake's water, the concentration is 7 ng/L. What is this compound's octane-water partition coefficient?
Homework Answers
The octanol/water partition coefficient (Kow) is defined as the ratio of a chemical's concentration in the octanol phase to its concentration in the aqueous phase of a two-phase octanol/water system.
Kow = Concentration in octanol phase / Concentration in aqueous phase. here octanol phase is tetrachloroethene in trout in Lake Gouda and the aqueous phase is the lake's water. Also, 1 nanogram/liter or 1 ng/L = 0.000001 part per million.
The octanol-water partition coefficient Kow is used to predict and model the migration of dissolved hydrophobic organic compounds in soil and groundwater.

100 mL of aqueous solution containing 2,4,6-trinitrotoluene (TNT) at an initial concentration of 0.05 ppm is shaken with 10 mL hexane. After the phase separation, it was determined that the organic phase has 0.4 ppm. What is the partition coefficient, and what is the percent extracted? If the equilibrium concentration (rather than initial concentration) is 0.05 ppm, this would simplify the calculation. What would then be the partition coefficient and percent extracted?
