A Pourbaix diagram, also known as a potential-pH diagram, is a graphical representation used in electrochemistry to illustrate the thermodynamic stability of chemical species in an aqueous environment as a function of pH (alkalinity or acidity) and electrode potential (voltage). In a Pourbaix diagram: - The x-axis typically represents the pH of the solution, ranging from very acidic (low pH) to very basic (high pH).
