Problem 8: Assume that an aqueous sample contained traces of the following compounds listed in the table and that you extracted the aqueous Octanol-Water Distribution Coefficients COMPOUND NAME Benzene Toluene o-Xylene m-Xylene p-Xylene pk 2.13 2.73 3.12 3.20 3.15 ple with an aliquot of octanol. The distribution coefficients are given as pKD values. List the compounds in order of increasing concentration in the octanol phase at equilibrium Assume that you analyzed an aliquot of the aqueous sample using HPLC with a mobile phase of 75% methanol and 25% water on a C8 column. Predict the elution order and make a sketch of the predicted chromatogram. Label each peak. (a) (b)
