摘要

Abstract

Based on the relationship between the standard Gibbs free energy change, the standard electrode po-tential and the standard reaction equilibrium constant, the relationship between standard electrode potentials in differ-ent standard states has been analyzed. Accordingly, the general method to calculate the reaction equilibrium constant by designing a Galvanic battery is discussed, taking the dissociation equilibrium of water as an example.
