An episode of a popular crime investigation television episode used a separation techniques as part of the plot. Searching for clues of a crime, an extract from the vitreous humor of the eye (liquid in the eyeball) is examined for the presence of a particular drug. The procedure uses 0.010 L of non-polar toluene to extract the drug from 0.0050 L of vitreous humor? However, they also find that the drug has the properties of a weak base. B + H2O BH+ + OH-; Kb = 1.0 x 10-5. At pH = 7.80(and using a KD value of 5.8) what fraction of the basic drug would remain in 0.0050 L of the viterous humor? What fraction would appear in the toluene phase?
