氧化还原反应知识是中学化学基本理论的重要组成部分,掌握其解题方法是学习氧化还原反应中必须要突破的重难点.任何氧化还原反应都必须遵循其基本规律,在解题中巧妙利用此点会使部分氧化还原反应题型变得简单、清晰、明了.一、守恒律在氧化还原反应中,(1)氧化剂得电子总数与还原剂失电子总数相等;(2)氧化剂化合价降低总数与还原剂化合价升高总数相等;(3)反应前后电荷总数相等(离子反应). The knowledge of redox reaction is an important part of the basic theory of chemistry in middle school, mastering the problem-solving method is to study the red and red reaction must break through the heavy difficulty.Any redox reactions must follow its basic law, in the problem-solving clever use of this Point will make some of the redox reaction type becomes simple, clear and clear. First, the conservation law In the redox reaction, (1) the total number of electrons in the oxidant is equal to the total number of electrons lost by the reducing agent; (2) Reducing agent valence increased the total number of equal; (3) the total number of charge before and after the reaction is equal (ion reaction).
