✦ Synopsis

Impedance

measurements were performed on Iron m sulphate and chlonde media with varying additions of chlonde and sulphate respectively These experiments were performed wlthm pH &4 and current density up to 0 2 A cm-' The impedance diagrams showed a gradual transition from the lron-chlonde to Iron-sulphate systems These results were Interpreted on the basis of the previously proposed iron dissolution mechamsm
