二氧化碳制备与性质的两种微型化实验设计

Two Newly Designed Microscale Chemical Experiment Aboutthe Preparation and Properties of Carbon Dioxide

用启普气体发生器制取二氧化碳,存在药品的消耗量比较多,性质实验中二氧化碳的使用率不高的,污染环境等缺点,所以怎样改进该实验方法和装置,降低实验成本、减少污染是中学化学教学中需要解决的问题之一。本文所设计的二氧化碳制备及性质的两种微型化学实验新方法,与常量制备及性质验证的方法相比较,具有节约药品、操作简便快速,污染减少等特点。尤其是在环保、安全性、学生兴趣、方便性等方面都有一定优势的。

Using kipp gas generator to prepare carbon dioxide has some disadvantage as more reagent consumption,environment pollution and less utilization rate of carbon dioxide,so it is really necessary to improve theexperimental method and gas preparing device. Two newly microscale experiment method,which was faster and easier to the operation,were designed to prepare carbon dioxide. The new experimental method, especially, has certain advantages in environment protection,highly interest of students and safety operation.
