电解池电极反应的书写对于好多学生来说都是一个难点,要想正确快速地书写电极反应,笔者认为不仅要熟记离子放电顺序表,掌握电解规律和书写的步骤也很重要。以下是我在前人总结的基础上进行的归纳总结:一、根据物质的性质和存在状态,确定体系中的粒子种类别忘了酸性溶液中一定有大量的H+,碱性溶液中一定有大量的OH-,水溶液中既有H+又有OH-。
Electrolytic cell electrode reaction writing for many students are a difficult point, in order to write the electrode reaction correctly and quickly, I believe not only to memorize the ion discharge sequence table, grasp the laws of electrolysis and writing steps are also important. The following is my summary of the previous summary based on the summary: First, according to the nature of the material and the existence of the state to determine the species do not forget the acidic solution must have a lot of H +, alkaline solution must have a large number OH-, both aqueous H + and OH-.
