二、对喷泉的颜色进行广泛的思维我们首先要了解喷泉实验是怎样形成的。1.不难发现,本实验的喷泉颜色是由烧瓶中的气体(HC1)与烧杯中喷上来的石蕊溶液相互反应后形成的。因 HC1的水溶液呈酸性,所以遇石蕊溶液时就变成红色,从而看到美丽的红色喷泉。显见,喷泉的颜色是烧瓶中的气体与烧杯中的液体反应的结果。这样我们只要想出“气体与液体反应后生成有一定颜色的物质的反应”就行了。
Second, the fountain of color for a wide range of thinking we first need to understand how the fountain experiment is formed. 1. It is not difficult to find that the color of the fountain in this experiment was formed by the interaction of the gas (HC1) in the flask with the litmus solution sprayed in the beaker. Due to the acidity of the HC1 aqueous solution, it turns red when it encounters a litmus solution, so you can see the beautiful red fountain. Obviously, the color of the fountain is the result of the gas in the flask reacting with the liquid in the beaker. In this way, we just have to come up with “a reaction of a substance of a certain color after the gas and liquid react.”
