我对初中化学课本中设计的该实验做了改进。实验装置如图:实验步骤1.取一只干燥的锥形瓶和一只橡皮塞,在橡皮塞上钻一个小孔,插入一根粗铝线。铝线的一端用铁锤锤扁并弯成小铝勾,使其能托住小颗白磷为宜。另一端弯成直角。2.取一颗绿豆大的白磷放在铝勾上,将瓶塞塞紧。
I improved the experiment designed in junior high school chemistry textbooks. Experimental device as shown in the figure: Experimental steps 1. Take a dry Erlenmeyer flask and a rubber stopper. Drill a small hole in the rubber stopper and insert a thick aluminum wire. One end of the aluminum wire is hammered flat with a hammer and bent into small aluminum hooks so that it can support small white phosphorus. The other end is bent at right angles. 2. Take a large white phosphorus of mung bean on the aluminum hook and plug the stopper.
