WebFeb 29, 2012 · Abstract An equilibrium potential–pH (Pourbaix) diagram is presented for sulfur adsorbed on Ag (1 1 1). It allows prediction of the E –pH conditions of adsorption of sulfur and hydroxyl on silver surfaces immersed in water containing dissolved sulfur species such as sulfides. WebAug 17, 2024 · Pourbaix Diagrams plot electrochemical stability for different redox states of an element as a function of pH. [3] As noted above, these diagrams are essentially phase diagrams that map the conditions of potential and pH (most typically in aqueous solutions) where different redox species are stable.
