Abstract

THE NERNST EQUATION: ORIGINS AND THERMODYNAMIC CONTEXT. In the present article, the scientific journey that led to the development of the Nernst equation, a cornerstone in modern electrochemistry, is discussed. The paper not only explores historical achievements but also traces the evolution of scientific ideas and highlights the key figures who laid the conceptual and experimental groundwork for the seminal contributions of Nernst to the understanding of electrochemical systems. In this exploration, particular attention is paid to the examination of the first three articles published by Nernst between 1888 and 1889. These essential works marked the inception of the engagement of Nernst with the Leipzig Physical Chemistry circle, comprising the distinguished quartet: van’t Hoff, Arrhenius, Ostwald, and Nernst himself. Furthermore, the present study examines the intricate relationship between the Nernst equation and the four basic laws of Thermodynamics, all in an approach accessible to undergraduate students. A concise review elucidates the interpretation and significance of these foundational thermodynamic principles and explain how they hold the formulation of the Nernst equation.
