部编高一化学课本里《硫化氢的制取和性质》的实验,我将硫化氢的制取和性质两部分综合在一起,设计了一套实验装置。用这套装置进行硫化氢的制取和性质的实验,可以缩短实验时间,实验现象很明显,并且能防止有毒的硫化氢气体逸散到空气中去。一、实验装置下面是硫化氢的制法和性质的综合实验的装置图。这套装置可以分为三个部分:甲为自制的硫化
Department of Chemistry, a high textbook “Preparation and nature of hydrogen sulfide,” the experiment, I will hydrogen sulfide preparation and nature of the two parts together, designed a set of experimental devices. The hydrogen sulfide production and the nature of the experiment with this device can shorten the experimental time, the experimental phenomenon is obvious, and can prevent the toxic hydrogen sulfide gas escape to the air. First, the experimental device The following is a method of hydrogen sulfide and the nature of the integrated experimental device diagram. The device can be divided into three parts: A homemade curing
