SO_2气体性质实验包括制备装置、性质实验装置和尾气处理装置,在班级做演示时仪器较多难以携带,同时SO_2是有毒的气体,对环境有污染。为解决这些问题,笔者设计了一套微型装置。一、制作过程1.仪器及试剂:废弃的输液壶、输液袋(2个)、输液管、注射器(带针头)2个、Na2SO_2固体、稀硫酸。2.装置图(如附图所示)及装置的组装说明:(1)在干净的输液壶中加入Na_2SO_2固体,盖好输液壶胶塞,在胶塞上插一支吸有稀硫酸的注射器,使用时再将稀硫
The experiment of SO 2 gas properties includes preparation equipment, nature experiment equipment and tail gas treatment equipment. When the class is doing the demonstration, the instrument is more difficult to carry and the SO 2 is a poisonous gas which pollutes the environment. To solve these problems, I designed a set of micro-devices. First, the production process 1 instruments and reagents: waste infusion jug, infusion bag (2), infusion tubes, syringes (with needles) 2, Na2 SO_2 solid, dilute sulfuric acid. 2. Installation diagram (as shown in the figure) and assembly instructions of the device: (1) Add Na_2SO_2 solid in a clean infusion pot, cover the infusion pot stopper, insert a syringe with dilute sulfuric acid on the stopper , When used again dilute sulfur
