Abstract
Anodic corrosion of lead in sulfuric acid was studied in detail at potentials near the reversible potential. Results indicate that the first step in the corrosion process was reaction of lead with water to form lead dioxide. The solid‐phase reaction probably occurred below a certain potential, and this reaction plus two electrochemical reactions rendered lead dioxide unstable at lower potentials. A potential was found at which the corrosion rate reached a sharp peak. Above this peak lead dioxide was found in the reaction product.
