对高考化学试题的实验探究及启发

Experimental Inquiry on College Entrance Examination Questions of Chemistry

通过对2道高考试题的质疑，用实验探究的方法，回答了在氯化铵溶液里生铁的腐蚀类型，及二氧化硫通入硝酸酸化的硝酸银溶液是否会生成沉淀的问题，以此为基础，对高中化学教学中存在的某些问题进行了反思。

Through experimental inquiry, this paper studied the corrosion types of pig iron in ammonium chloride solution and whether precipitation will generate when sulfur dioxide was mixed with acidified silver nitrate solution. Based on this, some problems in the chemistry teaching in senior high school were reflected.
