物质的性质及制备是近几年高考化学试题的重要考点之一。以物质的性质及制备为背景的试题涉及的知识面广、题型多变、思维发散空间大,能很好地考查学生元素化合物知识掌握情况和化学实验操作能力的高低,因此复习中要引起足够的重视。为使学生牢固掌握物质的性质及制备,现就这类试题的设置方式,谈谈复习时的应对策略。一、物质的性质物质的性质分物理性质和化学性质。物质 The nature of the material and preparation is one of the important test sites for the college entrance examination chemistry test in recent years. Questions on the nature of the material and the preparation of the background questions covered a wide range of knowledge, variety of questions, divergent thinking space, can well examine the knowledge of the students elemental compounds and chemical experiment operation ability level, so the review should be caused Pay enough attention. In order to enable students to firmly grasp the nature of the material and its preparation, the way to set up such questions is to talk about the coping strategies at the time of review. First, the nature of the material The nature of the material is divided into physical and chemical properties. substance
