Dependence of the Composition of the Anodic Layer on the Oxidation Potential of Lead in Sulfuric Acid
Source abstract
Abstract
Potentiostatic oxidations of lead in were performed in the potential range between −900 and +1400 mv (with respect to the mercury/mercury sulfate electrode). The anodic layer was subjected to x‐ray diffraction and chemical analysis. According to the phases present three potential ranges are discerned. From −956 to about −300 mv only is present. From −300 to +900 mv large amounts of and are formed as well as small amounts of , , or orthorhombic and . Above +900 mv the divalent lead compound content decreases, while that of . rapidly increases. Above +1200 mv . is formed.
