_aABSTRACT This study covered indirect electrolytic destruction of chlorinated organic acid in water using the Co (III/II) redox mediator. This study is conducted to provide an alternative way to reduce the pollutants to much less toxic. Indirect electrolysis was used to degrade the chlorinated organic acids. The cobalt (III/II) acted s a mediator. The set-up consists of electrodes and different voltages were used (3v, 6v, 9v and 12v) to determine the rate of degradation of monochloroacetic acid, , dichloroacetic acid and trichloroacetic acid. In the rate of degradation, time was measured and appearance of gray light purple indicates the end of reaction. The applications of a power source with a potential of 3v to the chlorinated organic acid species recorded the slowest time degradation and the application of a 12v potential showed the fastest time of degradation for the chlorinated organic acid species. The results showed that all chlorinated organic acids used were degraded through indirect electrolysis and there is a significant difference between the rate of degradation of the three acids.
