高中化学中几种氧化——还原方程式的配平

Keeping Balance of Several Oxidation-Reduc-tion Equations in the Textbook for High School

氧化——还原方程式的配平是化学教学中的难题,特别在高中化学中,学生尤感困难,本文是作者从自身氧化还原反应,有单质参加和有单质生成的氧化还原反应诸方面归纳出一种学生易于接受的方法即“抓1分子法”。

Keeping balncc of oxidation-reduction equation is a difficult problem in the chemical teaching, especially in high school. The author induced from a great wany materials a new mcthod, namely, 'grasp one molecule', which is readily accepted by strdents.
