The electromotive force of the reverse battery can be considered to be a function of the free energy change of the total battery reaction, or the difference between the gamvini potential in the battery. The galvini potential difference between each phase is unsightly, so it is impossible to obtain electric power through the potential difference of each intermediate phase.On the other hand, each battery reaction includes a reduction reaction process and a oxidation reaction process, so it can be considered to be a battery, battery electromotive The value follows an additional principle. Therefore, the relatively simple method is to take a half of him to do a reference, combination of various batteries and reference semi-cells, and take a series of relative electric potential values.
The most commonly used semi-battery is a standard hydrogen electrode, which is composed of a nitrogen ion solution plated with platinum black precious metal clavity, and is filled with pressure is L bar (ie LXLO'Pa, actually think is L ATM Hydrogen. This standard electrode cannot be implemented in practical applications, but can be defined as a scale.
The electrode potential can be defined as a potential difference between the two-terminal blocks of the selected half-cell and the standard hydrogen electrode (or its equivalent electrode), and assume that the electrode potential is OV, it is necessary to note that the electrode potential is observed The physical quantity is not affected by the battery conventional representation.
"The electrode potential of zinc is one 0.76V" means that when the battery consists of a standard hydrogen electrode and the zinc electrode, the voltage gauge is placed on the voltage value of the battery two wiring post. The electrode potential is not the potential difference of "metal and solution", nor is there a random value.
In addition to using standard hydrogen electrodes, the parameters of the battery (containing standard hydrogen electrodes) can be marked according to the reduction potential and oxidation potential of the electricity.
