The document addresses common misunderstandings about the physical meaning of absolute electrode potential and provides a thermodynamic derivation of the correct expression for this quantity. It discusses that three reference levels can be chosen to measure the absolute value of the electrode potential, but only one of these is suitable for meaningful comparison with physical parameters on a common energy scale. The document recommends a critically evaluated value for the absolute potential of the standard hydrogen electrode in water and other protic solvents. It emphasizes that the absolute electrode potential is the difference in electronic energy between a point inside the metal (Fermi level) and a point outside the solution. The recommended value for the absolute potential of the standard hydrogen electrode at 298.15 K is (4.44 ± 0.02) V. The document also critiques and refutes other values reported in the literature, highlighting their conceptual or methodological flaws. Additionally, it provides detailed calculations and references for the absolute potential of the standard hydrogen electrode in non-aqueous solvents.The document addresses common misunderstandings about the physical meaning of absolute electrode potential and provides a thermodynamic derivation of the correct expression for this quantity.
