摘要
对浓硫酸的几个性质(吸水性、脱水性、强氧化性、遇水放热性、催化性)实验进行了整合创新设计,解决了教材实验中的药品耗量大、不易操作、药品易撒落、易污染水源、耗时长、不适合学生分组实验等缺点。整合创新后设计的实验不仅操作简便、体现绿色实验理念,而且操作安全,适合中小学生开展课外活动。
This paper designed several properties experiments of concentrated sulfuric acid including water absorption,dehydration property,strong oxidizing property,exothermic property when contacts water and catalytic property,which solved disadvantages of related experiments in the textbook,such as large consumption of drugs,not easy to operate,easy spill of drugs,easy to pollute water,time-consuming,not suitable for the grouping experiments.The integrated and innovative experiments were green,easy and safe to operate,which were suitable for students to carry out extra-curricular activities.
