Abstract — Nickel passivation in 1 M H2SO4 in the presence of hydroxyazomethine derivatives (C = const) and chloride anions in variable concentrations was studied. Plots of the Ni passivation current vs. 
showed symbatic and antibatic changes, depending on the chloride concentration range. The results obtained were inter-preted in terms of the Linear Gibbs Energy Relation (LGER).
