过氧化钠的性质实验是中学化学实验教学的重点之一,在竞赛或课堂教学中,许多教师都抱怨实验繁杂、时间不足,结果演示慌忙。为解决这个问题,我特设计了一套进行过氧化钠性质实验的微型化装置,它不仅适合于教师演示,而且也适合于学生实验。整个装置简单,易于操作,实验效果良好,只
The experiment of the nature of sodium peroxide is one of the focuses of chemistry experiment teaching in middle schools. In the competition or classroom teaching, many teachers complain that the experiment is complicated and the time is insufficient, and the result is hurried. To solve this problem, I specially designed a miniaturized device that has undergone sodium oxide properties experiments. It is not only suitable for teacher demonstrations but also suitable for student experiments. The whole device is simple, easy to operate, and the experimental results are good, only
