简易的H_2S、SO_2组合微型化实验装置

The Simple Combined Microminiaturization Experiment Device of H_2S and SO_2

硫化氢、二氧化硫的制备和性质实验在《无机化学实验》中是分别进行的，在常规教学中操作步骤多，药品用量多，污染严重．作者通过改进，将两部分实验利用微型化装置组合成一体，操作简便、安全、成本低、污染少、效果好。

The preparation and properties experiments of H2S and SO2 are done respectively in the experi- ment of inorganie chemistry. They have many operation steps in conventional teaching, need more chemi- cals and cause serious pollution. The writer combines the two parts of experiments by using microminiatur- ization device to make them simple, safe, cow cost, less pollution and effective.
