笔者甲、乙、丙、X的化学性质(氧化还原性、酸碱性、络合性)三个角度来分析哪些物质能实现题目所列转化关系.一、利用变价元素的还原性调整氧化剂用量来实现上述转化关系1.当X是氧化剂时,该转化关系从左到右体现的是连续氧化反应(1)甲、乙、丙含有同一种变价元素,其中甲和乙都具有还原性,甲、乙、丙中的变价元素价态越来越高,甲和丙反应生成含有变价元素中间价态的乙.换言之,过量的还原剂甲和少量的氧化剂X反应生成甲的
Author A, B, C, X chemical properties (redox, acid-base, complex) of the three angles to analyze what material can achieve the conversion listed in the topic. First, the use of variable elements of reducing the amount of oxidant To achieve the above conversion relationship 1. When X is the oxidant, the conversion relationship from left to right is the continuous oxidation reaction (1) A, B, C contains the same variable elements, which A and B have a reducing, A , B, C in the price of elemental valence is getting higher and higher, A and C reaction containing valence element price valence B. In other words, excessive reductant A and a small amount of oxidant X reacts to form a
