氢氧化亚铁制备的实验改进 人教版普通高中课程标准化学1（必修）第三章第二节《几种重要的金属化合物》中制备Fe(OH)2是对照Fe(OH)3的制备方法。制备出的Fe(OH)2由于和空气接触，极易被空气中的O2氧化，学生基本上看不到白色絮状沉淀。本文通过以下两种方法对氢氧化亚铁制备的实验进行改进，均获得较好的效果。 |

| 正文翻译： The preparation of ferrous hydroxide introduced in "several important metal compounds", sectionⅡ of Chapter Ⅲ, common high school chemistry curriculum standard one (compulsory, published by PEP), is referred to the iron hydroxide preparation method. The prepared ferrous hydroxide is exposured in air, which can be easily oxidized by oxygen. Thus, students generally can not see a white flocculent precipitate. In this paper, two improved methods of experimental preparation of ferrous hydroxide are discussed, showing better performance. |

正文：According to content in "several important metal compounds", sectionⅡ of Chapter Ⅲ, common high school chemistry curriculum standard one (compulsory, published by PEP), ferrous hydroxide is synthesized, referring to the preparation of iron hydroxide. The resulted ferrous hydroxide is easily oxidized due to the exposurement to air. Thus, the white flocculent precipitation could be hardly observed. In the paper, two methods for improving the preparation of ferrous hydroxide are discussed. 感觉中文有些词可以完全不翻译，而且英语单词不宜重复过多！ |
