本文根据苏教版专题4第二单元《生产生活中的含氮化合物》的教学内容,对NO、NO2性质和稀HNO3与Cu反应、浓HNO3与Cu反应的实验教学过程进行了改进与整合,对实验中所得的Cu(NO3)2溶液颜色的不同进行了解释,并对该部分的教学内容通过以实验为主线进行整合的教学过程进行了分析,探讨了如何提高学生学习化学的积极性和课堂教学效率。
Based on the teaching content of the second unit “Production and Living Nitrogen Compounds” of the 4th edition of the Sujiao edition, this paper improves and integrates the experimental teaching process of the reaction of NO and NO2 with the reaction of dilute HNO3 with Cu and the reaction of concentrated HNO3 with Cu, The differences of the color of Cu (NO3) 2 solution obtained in the experiments were explained, and the teaching contents of this part were analyzed through the process of experiment integrating the main line, and discussed how to improve students’ enthusiasm in learning chemistry and the classroom Teaching efficiency.
