推断题可以算化学中最难的一类题型。它涉及的知识面最广,主要是根据已知现象用物质特性进行分析推断,先读题,全面审题,根据实验现象分析,找突破口,往往题中物质的组成、颜色、溶解性、化学性质等特性是解决问题的突破口,也就是说看其颜色、观其状态、察其变化。根据题意,用特殊的现象或反应关系进行正向或反向的逻辑推理。如果有图示的推断题可将题中的信息写到方框对应物质的旁边,推断时只看方框中物质的反应关系。
Inferred questions can be counted as the most difficult type of chemistry questions. It involves the most extensive knowledge, mainly based on the known phenomenon with the material properties of the analysis inference, first reading, comprehensive examination, according to the analysis of the phenomenon of the experiment to find a breakthrough, often the title of the material composition, color, solubility, chemical properties And other characteristics of the breakthrough point is to solve the problem, that is to look at the color, view the status, observe its changes. According to the inscription, with a special phenomenon or response to the relationship between forward or reverse logical reasoning. If there is a pictorial inference, the information in the question can be written next to the corresponding substance in the box, inferring only the response of the substance in the box.
