| Abstract: | Based on the relationship between the standard Gibbs free energy change, the standard electrode potential and the standard reaction equilibrium constant, the relationship between standard electrode potentials in different 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. |
