氧化还原反应是中学化学中的重要的教学重点之一。氧化还原反应广泛地用于工农业以及科学行业和日常生活中。由于有的氧化还原反应特别复杂,不可能利用观察法配平该反应。在高考关于此类概念中常以选择和填空题的形式出现。一、关于氧化还原反应配平的几种方法1.从反应的正向(进行方向)配平法此方法可用于分子之间的氧化还原反应和所有元素都参与氧
Redox reaction is one of the important teaching focuses in middle school chemistry. Redox reactions are widely used in industry and agriculture as well as scientific industries and daily life. Due to the particular complexity of some redox reactions, it is not possible to trim the reaction by observation. In the college entrance examination on such concepts often appear in the form of choice and fill in the blank. First, the redox reaction on the balance of several methods 1 from the reaction of the forward (direction) trim method This method can be used for the redox reaction between molecules and all elements involved in oxygen
