"The apparent valence of lead was determined in one normal solutions of potassium nitrate, ammonium acetate, lead nitrate, and lead acetate at temperatures of 25 and 50°C. The current density was varied from 0.001 to 1.00 amp•cm -2. The apparent valence of lead ranged between 1.90 and 2.00 in all solutions. The lower valences were reached at higher current densities. The amount of disintegration was very small, and was dependent upon film formation on the surface of the anode.
Potential-current density relationships for the anodic dissolution of lead were obtained in the electrolytes mentioned above. In potassium nitrate and ammonium acetate solutions, the Tafel slopes were 0.030 volts. The proposed dissolution mechanism is
Pb(s) → Pb+(s) + e (fast)
Pb+(s) → Pb+2(s) + e (fast)
Pb+2(s) → Pb+2(aq) (slow)"--Abstract, page ii.
