The aim of this work was to investigate the stability of the gold complex based on mercaptotriazole at optimum pH value of nine in the electrolyte with gold concentration of 1.5 g/dm3. Investigations were performed by visual monitoring and electrochemical characterization of electrolytes over the period of four months. The first visible signs of the decomposition of the complex were appeared one month after synthesis. Electrochemical characterization of gold complex base on mercaptotriazole performed by the open circuit potential measurement, cycling voltammetry method, and recording the polarization curves, with pH of the electrolyte measurement before and after each electrochemical experiment, showed that all the recorded characteristics remained almost unchanged for a period of four months.
