摘要
对现行教材及文献中铜与浓硫酸反应实验设计的优点和不足进行了分析,并在借鉴已有研究的基础上,秉承绿色化和微型化的实验设计理念,对该实验装置进行优化改进.通过利用一次性注射器和Y型管,使得整个实验过程在封闭系统中进行,实验现象明显的同时减少了药品用量,简化了操作步骤,尾气吸收彻底.
This paper analyzed the advantages and disadvantages of the experiment designs of reaction between copper and concentrated sulphuric acid,which were presented in the current textbooks and literatures. With the thought of greenization and miniaturization, using disposable syringes and Y-shaped tube, this article improved the experiment device, the whole experiment procedure could be finished in a closed system, and this experiment had the advantages of less dosage, simple operation, obvious phenomena and green.
