Abstract :In this study the electrochemical behaviour of gold electrode in 0,5 M acetic, succmic and citric acid Solutions was investigated by the help cf current-potential curves. It was obser- ved that the potentials where the anodic current starts to flow shifted towards more positive values and the average thickness of the oxide layer (L) grew as a number of COOH group in the acid was increased. The oxide coverage ratio 0oX increased and the organic coverage ratio 0org decreased as the medium was changed from 0,5 M acetic acid to 0,5 M citric acid.Keywords : In this study, potentials where the anodic, acid was increased
