电解是使电流通过电解质溶液(或熔融电解质),而在阴阳两极被迫引起氧化一还原反应的过程,也就是说电解是在电流强制下发生的氧化一还原反应,它是一种最强有力的氧化还原方法。电解过程中,电子从电源负极移向电解槽的阴极,再从阳极回到电源的正极。阳极发生氧化反应,阴极发生.还原反应。电解产物以及电极是否溶解与电解质的本性、浓度、电流强度、电极材料等因素密切相关.在结合如下几例略谈电解过程中两极溶液和电解后的残存液性质变化原理。
Electrolysis is the process of passing an electric current through an electrolyte solution (or molten electrolyte), and the yin and yang electrodes are forced to cause an oxidation-reduction reaction, that is, electrolysis is an oxidation-reduction reaction that occurs under the force of an electric current, and it is the most powerful The redox method. In the electrolysis process, electrons move from the negative pole of the power source to the cathode of the electrolytic cell and then from the anode back to the positive pole of the power source. The anode undergoes an oxidation reaction and the cathode undergoes a reduction reaction. Electrolysis products and whether the electrode is dissolved is closely related to the nature of the electrolyte, concentration, current intensity, electrode material and other factors. In the following several examples, the principle of the nature change of the bipolar solution and the residual liquid after electrolysis in the electrolysis process is briefly discussed.
