过氧化氢分解反应实验,设备简单,直观性好,是个很好的教学实验。目前的教材中仍有采用。但是,该实验的量气装置多为立式。测量时需随时保持液面平齐。这给操作和读数带来不便。本文设计制做了一种水平量气装置。多次使用表明,操作方
The hydrogen peroxide decomposition reaction experiment is simple and intuitive. It is a good teaching experiment. The current teaching materials are still used. However, the gas measuring device for this experiment is mostly vertical. Keep the liquid level at all times while measuring. This brings inconvenience to operation and reading. This article designed and manufactured a horizontal gas device. Multiple use indicates that the operator
