二氧化碳系列实验的创新改进

Improvement of Series Experiments of Carbon Dioxide

在复习课中，设计了综合实验装置，能够完成二氧化碳的制取，二氧化碳与水反应生成碳酸，碳酸具有不稳定性，二氧化碳一般情况下不可燃、不助燃及密度比空气大，二氧化碳与澄清石灰水反应的系列实验。实验器材普通，操作简单，现象明显，可用于多个平行班的实验演示和探究。

This paper designed comprehensive experiment device in review lesson, it could finish a series of experiments including the preparation of carbon dioxide, reaction of carbon diox- ide and water, instability of carbonic acid, non-flammable and non-combustion of carbon dioxide, and so on. The experiment equipments were common, the operation was simple, the phenomena were clear, and it could be used for experiment demonstration and inquiry in multiple parallel classes.
