摘要
利用蒸发皿和表面皿组成的"气室"实现二氧化硫的制备及性质实验,充分呈现了二氧化硫的酸性、漂白性、氧化性和还原性。方法具有装置简单、试剂量少、污染小的特点,是一个集微型化与绿色化于一体的实验。
The preparation and properties of sulfur dioxide were tested by using a gas chamber composed of evaporating dish and watch glasses.The experiment fully shows the acidity,bleaching,oxidizing and reducing properties of sulfur dioxide.The method has the characteristics of simple device,less test dose and less pollution.This is an experiment integrating miniaturization and greening.
