一、改进实验名称二、改进实验目的二氧化碳是学生日常生活中比较熟悉的物质,与人们生活和生产实际有着紧密联系,而它的制取和性质实验也是中学化学实验教学的重点之一,所用药品在家庭中也容易找到,对它的研究学生会比较感兴趣,也可以趁机调动起学生的积极性和主动性。为了解决这个问题,特设计了一套在家庭中进行二氧化碳制取和性质实验的装置,它不仅适合于学生家庭实验,而且也适合于教师演示,整个装置简单,易于操作,实验效果良好。
First, to improve the experimental name Second, the purpose of improving the experiment Carbon dioxide is a familiar material in daily life of students, and people’s lives and production are closely linked to the actual production and nature of its experiment is also one of the key chemical experiment teaching, Drugs are also easy to find in the home, students interested in researching it can also take the opportunity to mobilize the enthusiasm and initiative of students. In order to solve this problem, we designed a set of devices for carbon dioxide production and characterization experiments in the home. It is not only suitable for students’ home experiments, but also suitable for teacher demonstration. The whole device is simple, easy to operate and experimental results are good.
