Abstract: The dissociation constant of PAOx was determined spectro-photometrically in the presence or absence of surfactants. The state of PAOx in aqueous solutions was studied by using spectro-photometric and quantum chemical methods. The tautometric equilibrium is shifted to the quinone-hydrazone form in the presence of CTMAB.

Key words: Solution equilibrium, Pyridylazo, Hydroxyquinoline
