在我们进行“氨碱法”的教学时,应使学生懂得“氨碱法”的生产原理,所以,在中学化学教学大纲(草案)中规定了“将氨、二氧化碳通入饱和食盐溶液以制取碳酸氢纳”教师应进行演示实验。我们认为这样规定是符合于实行基本生产技术教育的要求的。我们把一向进行这个演示实验的装置和操作写出来希望和同志们一起来研究和改进。
When we carry out the teaching of “ammonia-alkali method”, we should make the students know the production principle of “ammonia-alkali method”. Therefore, in the chemistry teaching outline of secondary school (draft), we stipulate that “ammonia and carbon dioxide are fed into saturated salt solution Take sodium bicarbonate ”teachers should conduct demonstration experiments. We think such a provision is in line with the requirements of implementing basic production technology education. We have written about the installation and operation that has been carrying on this demonstration experiment in the hope of working with the comrades to study and improve it.
