To simplify understanding and maintain rigor in the presentation of material on fundamental electrochemistry and electroanalytical chemistry, a correct phase equilibrium condition has been introduced for deriving the fundamental equation of electrochemical thermodynamics. A potential jump at the metal/metal interface has been eliminated. A "reversible electrode reaction" has been determined. Parallels between cyclic and square-wave voltammetry have been explored. The nature of absolute potential has been defined. Examples of modern electroanalysis, including biosensors, are considered.
