一、NO_2与水的反应实验装置如图1所示。1.实验步骤(1)按图1组装好实验装置。实验前,在圆底烧瓶中收集一瓶NO_2气体,在分液漏斗中加入适量水。(2)打开分液漏斗活塞,使分液漏斗中的水全部流入圆底烧瓶中,立即关闭活塞。(分液漏斗上的玻璃塞始终打开)。(3)轻轻摇动圆底烧瓶,观察实验现象。(4)再次打开分液漏斗活塞,一会儿关闭。密切注意观察实验发生的现象。(5)再次轻轻摇动圆底烧瓶,然后观察实验现象。
First, NO 2 and water reaction Experimental device shown in Figure 1. 1. Experimental steps (1) assembled according to Figure 1 experimental device. Before the experiment, collect a bottle of NO 2 gas in a round bottom flask and add the appropriate amount of water to the separatory funnel. (2) Open the separatory funnel piston so that all the water in the separatory funnel flows into the round bottom flask and immediately close the piston. (Glass stoppers on the funnel always open). (3) Gently shake the round bottom flask to observe the experimental phenomenon. (4) Open the separatory funnel piston again and close it for a while. Pay close attention to observe the phenomenon of the experiment. (5) Shake the round bottom flask gently again and observe the experiment.
