物质的性质及制备实验题是近几年高考化学实验题的一大亮点,也是高考中的一个难点。分析近三年全国及各地高考化学试卷,发现大多数物质的性质及制备实验题越来越新颖,也越来越灵活,是对考生实验能力的一个很好的考查。因此,该专题是化学实验部分的重中之重,考生应引起足够的重视。【命题特点】对2010年～2012年各地高考有关“物质的性质及制备实验”考查的内容分析后发现,近三年各地高考化学实验题的呈现方式多是以物
The nature of the material and the preparation of experimental questions in recent years, a major highlight of the college entrance examination chemistry experiment, but also a difficult college entrance examination. Analysis of nearly three years of national and local college entrance examination chemistry papers, found that most of the nature of the material and preparation of experimental questions more and more innovative, more flexible, is a good test of the candidates ability to test. Therefore, the topic is the most important part of the chemical experiment, candidates should be given enough attention. 【Proposition characteristics】 2010 ~ 2012 around the college entrance examination on the “nature of the material and preparation experiment ” analysis of the contents of the examination found that nearly three years of college entrance examination chemical examination questions are mostly based on objects
