摘要
针对二氧化硫实验室制取及性质实验等进行整体化及微型化创新设计,使实验整体连续,一次性完成二氧化硫的制取及其漂白性、氧化性、酸性、还原性等性质的验证,仪器微型节约,现象清晰明显,实验结论正确,过程绿色环保.
The experiments of sulfur dioxide were integrated and micro-scaled to validate its properties such as bleachability,oxidizability,acidity,reductibility and so on. It was found that the experimental phenomena were more obvious,the conclusion was correct,and the process was going green and environmental protection on a micro-scale experiment.
