废铁屑制备三草酸合铁酸钾虚实结合的综合化学实验设计
Virtual and Actual Comprehensive Chemical Experimental Design on Preparing Potassium Ferric Oxalate from Scrap Iron Filings
摘要
Abstract
In this experiment,the preparation of ammonium ferrous sulfate and potassium ferric oxalate,and the determination of iron ion,oxalate ion and crystal water content were integrated to develop a comprehensive chemical experiment.In the preparation part,virtual operation and independent design were introduced.In the analysis and detection part,not only the traditional chemical analysis method was used,but also the infrared spectrometer and X-ray diffractometer were introduced to characterize the product.The experiment can make the students consolidate the basic laboratory skills such as vacuum filtration,recrystallization and titration,master the instrumental for characterizing the composition and structure of products,which can train students'ability to comprehensively apply chemical theoretical knowledge to solve practical problems and develop good scientific research literacy.Furthermore,by combining with ideological education,this experiment can also help cultivate students'environmental protection awareness and scientific exploration spirit,and improve students'sense of responsibility in the laboratory and interest in chemistry.关键词
