Abstract: The dissociation of DBC-Arsonazo in aqueous solution was studied by spectro-phtometric and potentiometric litration meiricdr.The values of dissociation constants,pK1=0.70,pK2=1.68,pK3=2.76,pK4=6.54,pK5=9.64,pK6=10.54,were determined by spectrophotorr.ctric methods at the identical temperature and ionic strength (20℃,I=0.4).Under the identical conditions the results pK3=3.7,pK4=6.67,pK5=9.95,pK6=10.95,obtained by using the potentiometric titration method.
