二氧化碳和二氧化硫是一对孪生兄弟,在化学性质上有诸多的相似,但又不完全相同。很多学生对二者性质混淆不清,现对比归纳二者性质的异同,希望对学生的学习有所帮助。案例:(1)将CO_2通入BaCl_2溶液中至现象明显(2)将CO_2通入Ba(NO_3)_2溶液中至现象明显(3)将SO_2饱和溶液滴加到BaCl_2溶液中至现象明显(4)将SO_2饱和溶液滴加到Ba(NO_3)_2溶液中至现象明显
Carbon dioxide and sulfur dioxide are twin brothers and have many similar but not identical chemical properties. Many students are confused about the nature of the two, and now compare the similarities and differences between the two, hoping to help students learn. Case: (1) Addition of CO_2 into BaCl_2 solution obviously (2) Addition of CO_2 to Ba (NO_3) _2 solution was obvious (3) SO_2 saturated solution was dropped into BaCl_2 solution obviously ) The saturated solution of SO 2 was added dropwise to Ba (NO 3) 2 solution to the phenomenon is obvious
