中学生化学实验信息整合能力的培养模式中,要求学生在获得足够的信息基础上能够大胆提出假设,对原有的实验信息持有怀疑的辩证态度。很多教师都写到过检验的方法,将高中涉及到的溶液中存在的离子全部考虑到位,论述的方法也很全面。但是不足的是没有脱离常规的角度,在教学中没有做到创新的层面。本文就高中硫酸根离子的检验大胆提出假设,应用“碱化法”检验硫酸根离子。 In the cultivation mode of middle school chemistry experiment information integration ability, students are required to make bold assumption on the basis of obtaining sufficient information and hold a skeptical dialectical attitude to the original experimental information. Many teachers have written about methods of inspection, taking into account all the ions present in the solution in high school, and the methods discussed are also comprehensive. But what is not enough is that it has not departed from the conventional point of view and has not made an innovation in teaching. In this paper, we made a bold assumption about the test of high school sulfate ion. We use the method of “alkalization” to test the sulfate ion.
