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
For example, in the classical work of Landsberg and Bartelt 1, the equation (i-i~)r~ = k indicates that below i I the electrode will not passivate owing to the mass transfer limitations in solution, i~ is the current density equivalent to transfer of mass from the electrode by processes other than d
The dissolution of nickel ferrite in oxalic acid and in ferrous oxalate-oxalic acid aqueous solution was studied. Nickel ferrite was synthesized by thermal decomposition of a mixed tartrate; the particles were shown to be coated with a thin ferric oxide layer. Dissolution takes place in two stages,
