无机推断题可以取材于化学基本概念、化学反应原理、元素化合物知识以及化学实验和化学计算等多个知识板块,具有命题素材广泛、体现能力立意、试题区分度好等特点,而且试题的情景、设问方式、综合性、难度、分值等可以灵活地调节和设置,创新空间广阔。本文主要针对三类无机推断题的解题依据和解题策略予以归纳和点拨,供学生参考。题型一离子推断题试题所呈现的实验现象(即离子的性质)、离子共存规律、电中性原理是突破离子推断题
Inorganic inference questions can be drawn from the basic concepts of chemistry, chemical reaction theory, chemical compounds and knowledge of chemical experiments and chemical calculations and other knowledge section, with a wide range of proposition materials, reflecting the ability of meaning, the test of the degree of distinction is good, and the test scenarios, Set the way to ask, comprehensive, difficult, points, etc. can be flexibly adjusted and set, a vast space for innovation. In this paper, three types of inorganic inference problems and solutions based on problem solving strategies to be summarized and tips for students to reference. Examine the problem of an ion inference questions presented by the experimental phenomena (ie, the nature of the ion), ion coexistence, the principle of neutral electricity is to break the problem of ion inference
