一、基本知识新解在氧化还原反应中,还原剂将电子转移给氧化剂,所以,氧化还原反应的实质就是电子转移的过程。那么如果把氧化剂和还原剂分开放置,用一根导线把氧化剂和还原剂连接起来,则电子就会沿着导线定向由还原剂流向氧化剂,所以在外线路中,就有了电流。如果把氧化还原反应中的氧化剂放在正极,还原剂放在负极,就能对外供电。因此,严格地说,所有自发的氧化还原反应,都可以做成原电池。而在可逆电池中,
First, the basic knowledge of the new solution In the redox reaction, reducing agent will transfer electrons to the oxidant, so the nature of the redox reaction is the process of electron transfer. Then, if the oxidant and the reducing agent are separated, and a oxidant is connected to the reducing agent by a wire, the electrons will flow from the reducing agent to the oxidant along the wire, so that in the external circuit, there will be an electric current. If the oxidant in the redox reaction is placed on the positive electrode and the reducing agent is placed on the negative electrode, external power supply can be provided. Therefore, strictly speaking, all spontaneous redox reactions can be made into primary batteries. In a reversible battery,
