有毒气体制备及性质联合实验的微型化设计

Micro-design of Joint Experimental in Preparation and Property of Toxic Gases

通过对中学化学实验现状分析,又根据微型化学实验可节省化学药品、减少污染、省时、安全等优点,本文用一些废弃品设计了实验装置。研究了部分有毒气体制备及性质的联合实验,并取得良好的实验效果。

This paper analysis the present condition in middle school chemistry experiment. By the fact that microscale chemical experiment have the advantages of safety, saving chemicals and raw materials , reducing pollution and saving time, this paper propose a method of using waste materials to design experimental devices. Joint experiments of preparation and properties of some toxic gases have been studied and experimental results show that this method is useful and efficient.
