一、二氧化碳溶解性实验的创新设计1.教材实验的不足(1)需要组装二氧化碳发生装置,检查装置气密性,然后收集气体,整个实验过程所用仪器多,操作繁琐,耗时长。(2)只能定性说明二氧化碳的溶解性。(3)趣味性不强。针对上述不足,笔者通过大量实验,对其进行了改进。2.创新设计(1)定性实验设计取一个完好的软塑料饮料瓶,如矿泉水瓶等,拧紧瓶
First, the innovative design of carbon dioxide solubility experiment 1. Insufficient teaching experiment (1) need to assemble carbon dioxide generating device, check the device air tightness, and then collect the gas, the entire experimental process using more instruments, cumbersome operation, time-consuming. (2) can only qualitatively explain the solubility of carbon dioxide. (3) is not interesting. In response to the above shortcomings, the author through a large number of experiments, to improve it. 2. Innovative design (1) qualitative experimental design Take a good soft plastic beverage bottles, such as mineral water bottles, etc., tighten the bottle
