With the size of the electrolyte decomposition voltage of the nature and electrolysis conditions

Electrolysis of the electrolyte required minimum applied voltage is called decomposition voltage. Also called decomposition potential or decomposition potential. With the size of the electrolyte decomposition voltage of the nature and electrolysis conditions (electrode material, the electrolysis temperature, current density, and solution concentration, etc.) are not identical and each different. Its value can be determined by the Nernst equation, also called the theoretical  air circuit breaker . The electrolyte in the electrode decomposition products of electrolysis required minimum voltage is applied. mcb circuit breaker   voltage of the electrolyte  mcb circuit breaker  of the raw product by electrolysis electromotive force, the yin and yang overpotential and electrode polarization voltage drop circuit composed of three parts. Electrolyte in the electrolyte, the second electrode is formed on the primary products of electrolysis cells, which force opposite the direction of electrolysis, the applied voltage is first have to overcome this force. This back electromotive force, equal to the second electrodes, the potential difference between the equilibrium. That is, for the theoretical decomposition voltage of the electrolyte.
