无机化学反应分为氧化—还原反应和非氧化—还原反应两种类型。其中,氧化—还原反应在日常生活、药品检验、土壤分析等方面都会遇到。在职工中专化学课中,氧化—还原反应也是重要的教学内容之一。本文就如何准确掌握氧化—还原反应的概念、类型和配平方法谈点体会。一、氧化—还原反应的类型氧化—还原反应的实质是电子得失(或转移),表现的特征必然是元素化合价的变化,化合价升高被氧化,化合价降底被还原。根据化合价的变化就可确定是否是氧化—还原反应。在无机化学反应中,元素的原子或者离子失电子(或电子对偏离),则化合价升高、被氧化;元素的原子或离子得电子(或电子对偏向),则化合价降低,被还原;
Inorganic chemical reactions are divided into two types of oxidation-reduction reaction and non-oxidation-reduction reaction. Among them, the oxidation-reduction reaction in daily life, drug testing, soil analysis and other aspects will be encountered. In the technical secondary school workers, oxidation - reduction reaction is also one of the important teaching content. This article on how to accurately grasp the concept of oxidation - reduction reaction, type and grading methods to talk about experience. First, the type of oxidation - reduction reaction The essence of oxidation - reduction reaction is lost or lost (or transfer), the characteristics of the performance is bound to change the elemental valence, valence is oxidized oxidation, valence reduction is reduced. According to the valence change can determine whether the oxidation-reduction reaction. In inorganic chemical reactions, elements of the atom or ion loss of electrons (or deviation from the electron), the valence is increased, oxidation; elements of the atom or ion electron (or electron pair bias), the valence is reduced, is reduced;
