In these additional titrations n-octanol is added to a solution of the substance in water and the apparent pKa of the substance in the two-phase system is measured.
T e S S 000654 K O W 5531displaystyle t_ eSS000654cdot K_ OW5531 For a substance with a log K OW of 4 it thus takes approximately five days to reach effective steady state.
The assumption behind this is that the uptake of an organic substance is driven by its hydrophobicity. Log b x y log b x log b y Logarithm quotient rule. Consider the below example. Lets assume that we are required to find the log base 10 for the numbers 100 1000 100000.
