通过对无机化学教材知识的整合,绘制自由能变-氧化值图和各物质间转化图,由点到线,由线连网,将氯元素零散的知识点归纳成知识体系,以期学生能更好地掌握元素相关内容,提高教学质量.
By drawing the free energy change and oxidation number diagram, and the materi- al transformation diagram, scattered knowledge points of chlorine element were integrated into a system, which was beneficial for students to master inorganic chemistry. The practical application indicated that it played an active role in improving teaching quality.
