氧化还原反应方程式的配平,是中学化学教学中的一个重点,也是高考中的一个常考点。所以,学生在学习的过程中能掌握一定的配平技巧尤为重要。氧化还原反应配平的方法有很多种,其中,最基本、使用最广泛的方法是“化合价升降法”。本文着重介绍如何快速的选出“化合价升降法”配平氧化还原反应的突破点,从而正确地配平方程式。
Balancing the redox equation is a key point in chemistry teaching in middle school and also a common test point in college entrance examination. Therefore, students in the learning process to master some of the trim skills is particularly important. Redox reaction trim there are many ways, of which, the most basic and most widely used method is “valence lift method ”. This article focuses on how to quickly select the breakthrough point of the “valence lift method” to trim the redox reaction, so as to correctly formulate the equation.
