ABSTRACT:

The electrochemical behaviour of iron electrode in different concentrations of NaOH solution was studied using cyclic voltammograms and A.C. Impedance techniques. Four anodic peaks (A1-A4) were observed in the anodic scan of cyclic voltammograms where two cathodic peaks (C1 and C2) were observed in the cathodic scan of cyclic voltammograms. The four anodic peaks due to the formation Fe(OH)ads peak (A1), Fe(OH)2, peak (A2), Fe2O3(peak A3) and formation of more stable Fe(III) species (peak A4) and the cathodic scan due to the reduction of species formed on the anodic scan.
