逆向法配平氧化──还原反应方程式银川一中刘艳萍对于刚接触较复杂的氧化一还原反应方程式配平的学生来说，学会化合价升降法配平氧化─还原反应方程式有利于他们对基本概念的理解。教学这部分内容的难点在有些氧化一还原反应方程式用上述方法配平，学生感到不好理解和不... Reverse Method Balanced Oxidation – Reduction Equations Yin Chuan Yizhong Liu Yanping For students who are just getting in touch with the more complex oxidation-reduction equations, it is beneficial for them to understand the basic concepts by using the valence reduction method to balance the oxidation-reduction equation. The difficulty in teaching this part of the content is that some of the oxidation-reduction equations are trimmed with the above method, students feel uncomfortable and not...
