氨氧化制硝酸的演示实验,在新教材选修模块《化学与技术》《实验化学》中都设计为如图1所示的装置:也许是受此影响,在高校的教学论实验中也和中学教材中的实验装置完全一样,或者区别不大。在中学化学教学法实验中,我们发现:如果按照这种装置来演示这个实验,一是仪器繁多和组装复杂,二是需要的氨水、催化剂和辅助试剂都较多,且不易成功,再则三 Ammonia oxidation nitric acid demonstration experiment, in the new textbook module “Chemistry and Technology” “Experimental Chemistry” are designed as shown in Figure 1, the device: may be affected by this, in the teaching of college experiments and high school Experimental equipment in the textbook exactly the same, or not very different. In the middle school chemistry teaching experiment, we found that if we demonstrate this experiment according to this kind of device, firstly, there are many instruments and complicated assembly; secondly, ammonia, catalyst and auxiliary reagents are needed more and are not easy to be successful; and then three
