电流通过电解质溶液而在阴阳两极引起氧化一还原反应的过程。叫做电解。那么如何熟练地掌握在电解过程中溶液里哪些离子参加电极反应,哪些离子不参加电极反应,是学习电解内容的解题关键。下面仅对酸、碱、盐溶液的电解过程,总结几点规律: An electric current passes through the electrolyte solution to cause oxidation-reduction reactions at the anodic and anodic poles. Called electrolysis. How to master the ions in the solution during the electrolysis process and participate in the electrode reaction, and which ions do not participate in the electrode reaction, is the key to solving the problem of electrolytic content. The following only summarizes the electrolysis process of acid, alkali and salt solutions.
