How much benzoic acid, Ka = 6.3⋅10-5, will remain undissociated in the aqueous phase of a 50 % oil-water emulsion if the initial concentration of benzoic acid in the aqueous phase is 0.5 %? The aqueous phase is buffered at pH 5. The true oil/water partition coefficient (for undissociated benzoic acid) is equal to 5.33. Assume that benzoic acid remains as a monomer in the oil phase.
