在初中化学全一册第114页和高中化学第一册第130页都有磷跟氯气反应的实验,过去作过多次实验,总不够理想,我们经过反复试验,设计出一套演示实验的简便装置。下面是我们的作法: 玻璃瓶装满水,将圆底烧瓶倒转过来底子向上,固定在铁架台上,并用带有两支导气管和曲柄铁匙的塞子塞紧瓶口,在匙中放上预先干燥的红磷。
In the junior high school chemistry first volume, page 114 and high school chemistry, the first volume, page 130 have phosphorus and chlorine reaction experiments, in the past made many experiments, always not ideal, we have repeated experiments, designed a set of demonstration experiments Simple device. Here’s what we did: Fill the glass bottle with water, turn the round bottom flask upside down, place it on the iron stand, and use a stopper with two air pipes and a cranked iron spoon to close the bottle mouth and place it in the spoon. Dry red phosphorus.
