In this paper were investigated the effect of hydrochloric acid concentration and addition of oxidizing agents on the rate of general corrosion of copper.For comparison, the corrosion rate in distilled water was also tested.Taffel extrapolation method was used for investigation of general corrosion of copper. Taffel extrapolation method implies scanning of working electrode potential on the order of ± 250 mV in relation to its Open Circuit Potential (EOCP), at the speed of 0.5 mVs-1.Investigations of corrosion were conducted in the corrosion cell according to Standard ASTM G5[5], on instrument potentiostat/galvanostat, Princeton Applied Research, model 263A-2, with the software PowerCORR®. Tests were performed at room temperature, 20 ± 1 °C.
