用代用品做焰色反应实验陆英麟（广西凌云中学５３３１００）鉴别金属阳离子方法之一是焰色反应，而焰色反应实验按课本要求需要铂丝和蓝色钴玻璃．铂丝很贵，不易买到，蓝色钴玻璃也很缺少，一般县级中学难以分组做焰色反应实验．我们通过实验摸索，可用代用品做焰色反应... Fire-color reaction experiment with substitutes Lu Yinglin (Guangxi Lingyun Middle School 533100) One of the methods to identify metal cations is the flame reaction, and the flame reaction experiment requires platinum wire and blue cobalt glass according to textbook requirements. Platinum wire is very expensive, not easy to buy, and blue cobalt glass is also very scarce. It is difficult for county-level middle schools to group flame-color reaction experiments. We explore through experiments, we can use substitutes to do the flame reaction...
