在全日制六年制重点中学侧重理科选修的高中一年级化学课本编写提纲卤素一章中,新增了歧化反应一节。本文将对歧化反应的定义,判断歧化反应的方向和限度予以简要介绍。一、歧化反应的定义氧化剂和还原剂是同一物质中同一元素的氧化还原反应,叫做歧化反应。例如,单质氯同氢氧化钠溶液作用生成次氯酸钠、氯化钠和水;加热氯酸钾分解生成氯化钾和高 A disproportionate response section was added to the chapter on Halogen Chemistry Textbook Preparation for Primary Schools with a focus on elective subjects in full-time six-year key middle schools. This article will give a brief introduction to the definition of disproportionation reaction and the direction and limits of disproportionation reaction. First, the definition of disproportionation reaction Oxidizing agent and reducing agent are the same element in the redox reaction of the same element, called disproportionation reaction. For example, elemental chlorine reacts with sodium hydroxide solution to produce sodium hypochlorite, sodium chloride, and water; heating of potassium chlorate decomposes to form potassium chloride and high
