氧化还原反应是一类有电子传递的反应。反应过程中,还原剂失去电子被氧化,氧化剂获得电子被还原。正由于反应时有电子在氧化剂和还原剂之间传递,因此,原则上,任何一个氧化还原反应都能安排成电池反应。各类电池都有一定的标准电动势E°为其特征,一个氧化还原反应所组成的电池亦应有一定的E°值。问题是这种E°值对于一个给定的氧化还原反应来说,是否只有唯一的一个呢?假若有几个电池,它们的电池反应完全相同,是否就
Redox reaction is a class of electron transfer reaction. During the reaction, the reducing agent loses electrons and the oxidant gets electrons to be reduced. It is due to the reaction of electrons in the oxidant and reducing agent transfer between, therefore, in principle, any one of the redox reactions can be arranged into a battery reaction. All kinds of batteries have a certain standard electromotive force E ° for its characteristics, a redox reaction composed of the battery should also have a certain E ° value. The question is whether this E [omega] value is the only one for a given redox reaction? If there are several cells, their cell reactions are exactly the same, and if so
