AImract--Galvanostatic experiments have been made on iron electrodes in hydrogen-poor and hydrogen-saturated alkaline solutions at 20Β°C. Emphasis was on the active behaviour of iron, but attention was also paid to its passivation. The mechanism of the anodic dissolution of active iron is found to b

Iron at -40" in acidic solutions of liquid ammonia displays an active region and a passive region. The dissolution reaction is pIGindependent and irreversible, the first charge transfer step being ratsdetermining. Passivation occurs through the adsorption of solvent oxidation products, initially pro
Abetract-The anodic passivation of iron was examined with respect to the degree of proton hydration as well as the acid structure. The investigation was based on the electrochemical tneasurements, XPS study and sulphur dioxide analysis. When acid concentration is low, the passivity of iron is a resu
The anodic behaviour of vanadium in acid solutions was studied in the presence of various anions and cations. Vanadium shows active hehaviour in all the solutions tested, except for some barium containing ones at pH >4, in which the metal is passivated at potentials positive to 0.09 V&e). It is foun
