离子推断题是高中化学学习中的重点和难点,离子推断题则是全面考查离子间的氧化还原反应、水解相互促进反应、复分解反应、配位反应等知识于一体的综合题。它要求同学们对题目要作全面细致的分析,并结合已知条件(现象、数据等)进行严密的推理。通常应从以下几方面入手: 1.审清题意,明确范围,注意题中所给的限制条件。 Ion inference questions are the key and difficult points in high school chemistry learning. Ionization questions are comprehensive questions that comprehensively examine the knowledge of redox reactions among ions, hydrolysis interactions, metathesis reactions, and coordination reactions. It requires the students to conduct a thorough and detailed analysis of the topic and combine the known conditions (phenomenon, data, etc.) for rigorous reasoning. Usually should start from the following aspects: 1. Review the meaning of the question, clear the scope, pay attention to the restrictions given in the question.
