利用粉笔开展绿色化学实验的探究

The Exploration of Using Chalk to Carry out the Green Chemistry Experiment

利用粉笔作载体进行离子鉴定、焰色反应等无机化学实验,并与试管、蒸发皿、坩埚等常用仪器的实验效果对比。实验结果表明,利用粉笔开展化学实验具有试剂用量少、操作方便、现象明显、无废液排放、绿色环保等诸多优点。

Chalk is used as the carrier to identify the ion,flame reaction and other inorganic chemistry experiment. It contrasts with the experiment effect of common instruments,for instance,vitro,evaporating dish,crucible,and shows many advantages. The experiment results show that there are many advantages using chalk to carry out chemical experiment,such as less reagent dosage,convenient operation,obvious phenomenon,no liquid waste emissions,green environmental protection and so on.
