Abstract In this study, employing an accurate and simple method of CvV and DV, combined with numerical simulation, FeCl3 was electrochemically examined in a 1 M HCl aqueous solution using Au working electrode. It was discovered that electrons exchange between Fe (III) and Fe (II) was a quasi-reversible process. CV was used to determine the electrochemical parameters of Fe (III)/Fe (II), such as D, Eo, ks and α values, which were then confirmed using a numerical simulation method. The nature of K3[Fe(CN)6] electrode reaction, in selected media at Au electrodes, was studied. It was determined that its mechanism occurred through moderately fast electrons transfer.
