这里介绍的三个无机化学演示实验,各有其特点。第一个实验是用简易快速的方法作出一个较难作的实验——水蒸汽与红热的铁反应;第二个实验是对氧化—还原反应的化学现象及电子转移同时反映出来;第三个则是改进传统实验方法,提高效果的鲜明性。实践表明,这些实验都能收到良好的效果。现分述如下: The three inorganic chemistry demonstration experiments presented here have their own characteristics. The first experiment is a simple and quick method to make a more difficult experiment - steam and red hot iron reaction; the second experiment is the oxidation-reduction reaction of chemical phenomena and electron transfer simultaneously reflected; the third One is to improve the traditional experimental methods, to enhance the effectiveness of the distinctive. Practice shows that these experiments can receive good results. Now as follows:
