一、无机推断题的解题方法在解无机推断题时,读题审题相当重要,在读题审题过程中要认真辨析题干中的有关信息,抓住突破口分析框图中的转化关系,仔细推敲,既要弄清楚明显的条件,又要挖掘出隐含的条件。解答无机推断题的关键是快速准确地找出突破口(即“题眼”),以突破口为中心,认真分析题意,选择合适的方法(顺推法、逆推法、综合推理法等)做出初步的判断,然后层层推进突破全题并加以验证,最后确定结果。无机推断题中解题的突破口一般是一些特殊的反应、特殊的反应现象、特有的反应条件、特殊的用途以及某些物质的特殊结构等,下面对无机推断题常见
First, the problem solving method of inorganic inference problems In the solution of inorganic inference questions, reading questions is very important, in the process of reading questions to carefully analyze the relevant information in the questions, seize the transformation of the breakthrough analysis block diagram, carefully scrutinized, It is necessary to clarify the obvious conditions and also to discover the hidden conditions. The key to solving inorganic inference problems is to quickly and accurately find out the breakthrough (ie, “topic of the eye”), take the breakthrough as the center, carefully analyze the meaning of the problem, and select the appropriate method (cis-push method, inverse method, comprehensive reasoning method, etc.) Make preliminary judgments, then push through the whole topic and verify it, and finally determine the results. The breakthroughs in solving problems in inorganic inference questions are generally some special reactions, special reaction phenomena, specific reaction conditions, special uses, and special structures of certain substances. The following are common questions for inorganic inference problems.
