物质的鉴别题是化学中考非常重要的一种题型,是建立在对物质性质深入理解的基础上的,综合性强,思维难度大。解决这类题,一定要根据设计的实验方案,观察不同的实验现象,从而一一区别开。笔者在复习这一部分内容时,偶遇一道题,难度较大。但却因此引发了一场实验探究,既解决了问题,又培养了学生的动手操作能力、思维能力和合作能力,收到了意想不到的 Material identification problem is a very important type of chemistry exam, is based on a thorough understanding of the nature of the material basis, comprehensive, thinking difficult. To solve these problems, we must observe the different experimental phenomena according to the designed experimental plan so as to distinguish them one by one. When I review this part of the content, I encountered a problem, more difficult. However, it triggered an experimental inquiry, which not only solved the problem but also cultivated students’ hands-on ability, thinking ability and cooperation ability and received unexpected results.
