Abstract: Protonation constants of some azo compounds were determined using the pH-metric and polarographic techniques. Also the polarographic behaviour was examined to throw some light on the reduction process of the studied compounds. The reduction process occurs through an irreversible 4-electron step corresponding to the reduction of the N=N centre. The resulted reduction peaks were used to quantify the mentioned compounds using cathodic stripping voltammetric technique.
