WebA Pourbaix diagram is a plot of the equilibrium potential of electrochemical reactions against pH. It shows how corrosion mechanisms can be examined as a function of … WebPourbaix diagrams :or eh‐pH, or pE‐pH diagrams can help environmental workers to “predict” the physical and oxidation state of a chemical element in different aquatic … WebPourbaix's diagram predicts that Pt metal will dissolve as Pt 2+ during anodic polarization in strong acid solutions. In sulfuric or nitric acid solution the electrolyte enhances the passivation of Pt, especially in 0.5–5 M solutions, and the extent of corrosion seems to be dependent on the formed platinum oxide, 91 which is presumably PtO. 90 In more … black bat flower zone
