Abstract :A comparative study on the reaction of o-chloro-, m-chloro-, p-chloro-, o, p-dichloro-, p- bromo-, and p-iodo- phenylazochromotropic acid with Pd insert ignore into journalissuearticles values(II); ions have shown that two 1:2 insert ignore into journalissuearticles values(metal: ligand); violet water soluble complexes are formed at two different pH values» The p-derivatives were found to be very suitable reagents for the spectrophotometric determination of Pd insert ignore into journalissuearticles values(II); up to 6.3-8.3 ppm. The application of these dyes as indicators in the spectrophoto¬metric titration of Pd insert ignore into journalissuearticles values(II); with EDTA and the effect of various cationş and anions on the determination were reported.
