where 𝐸 is the electrode potential under non-standard conditions, 𝐸 𝑜 is the standard electrode potential, 𝑅 is the universal gas constant, 𝑇 is the absolute temperature, 𝑛 is the number of electrons transferred in the electrode reaction, and 𝐹 is the Faraday's constant. This equation allows the determination of the electrode potential 𝐸 as a function of the pH of the solution.
