现行的人教版普通高中课程标准实验教科书中硝酸和铜的反应教材中没有设计实验。由于它在元素化合物、氧化还原反应等知识体系中的地位,以及实验现象和环境污染方面出现的问题,加之学生在初中阶段只是粗略地知道金属与硝酸反应不能得到氢气,对硝酸的强氧化性缺乏更直观的认识,所以在此大有必 There is no design experiment in the textbook on the reaction of nitric acid and copper in the current PEP Ordinary High School Curriculum Standards Experiment Textbook. Due to its status in the knowledge of elemental compounds, redox reactions and other issues, as well as experimental phenomena and environmental pollution problems, coupled with students in the junior high school stage, it is only roughly known that the reaction between metal and nitric acid cannot obtain hydrogen, and the strong oxidation of nitric acid Lack of more intuitive understanding, so this is a must
