The distribution ratio D for an analyte is defined as the ratio of its analytical concentration in two immiscible solvents (organic versus aqueous): D = Corg/Caq Show that the fraction of analyte remained in the aqueous phase after the extraction (from aqueous to organic) is given by the following: Fraction remained = Vaq/(VorgD + Vaq) where Vaq and Vorg are the volume of water and organic solvent used in the extraction, respectively.
