摘要
综合性实验——草酸亚铁的制备及其组成分析实验中,针对学生在实验过程中存在的诸多问题予以解释和改进,使学生的实验过程更加顺畅,提高了产品的产率、纯度及测定结果.同时,强化了学生综合实验能力的培养和综合素质的提高.
In the comprehensive experiment of the preparation and component analysis of ferric oxalate,a series of experimental improvement are introduced to solve the general problems which were frequently met across in the student experimental processes.The presented methods not only can make the experimental courses more smooth but also improve the yields and purities of the product accompanied with the more exact analysis of the components,which should be helpful to strengthen the comprehensive experimental skills of the students.
