【实验装置】实验组合反应器组装方式如图。【操作步骤】按照图中所示连接好仪器,把四根长10 cm粗铜丝从玻璃管①和③的上下口的胶塞插入管中做电极;并向管①和③中装入颗粒活性炭,目的是为了多吸附气体;从管②向管中注入30%氢氧化钾溶液,管②起调节压强、注入反应液和倾倒实验废液的作用,调整管②的高度,以排出玻璃管①和③里的空气,塞紧橡胶塞。检验气密性。
Experimental setup Experimental reactor assembly as shown. [Procedure] Connect the instrument as shown in the figure, insert four 10 cm long copper wires from the upper and lower openings of the glass tubes ① and ③ into the tube to make electrodes, and insert the tubes ① and ③ into the tube Activated carbon, the purpose is to adsorb more gas; from tube ② into the tube 30% potassium hydroxide solution, the tube ② from the regulation of pressure, into the reaction liquid and pour the role of experimental waste, adjust the height of the tube ② to discharge the glass tube ① and ③ in the air, plug the rubber stopper. Check air tightness.
