Abstract
Passivity in aqueous solutions is reviewed and several proposed
passivity models are outlined. Passivity in the non-aqueous solution
of acetic acid-acetic anhydride was observed and characterized by
voltage measurements. These measurements show a striking similarity
to those in aqueous solution. This suggests that the same basic process
is involved in both cases. Sulfuric acid, nitric acid, and chromium
trioxide were used as passivating agents in the non-aqueous medium
and their order is the same as in aqueous solution. The difference in
the actual species in solution raises the question of the applicability
of several of the passivity models outlined. Finally, suggestions are
made for experiments to clarify the passivation process using nonaqueous
passivated specimens.
