氫氧化亞鐵制備的實驗改進(jìn) 人教版普通高中課程標(biāo)準(zhǔn)化學(xué)1（必修）第三章第二節(jié)《幾種重要的金屬化合物》中制備Fe(OH)2是對照Fe(OH)3的制備方法。制備出的Fe(OH)2由于和空氣接觸，極易被空氣中的O2氧化，學(xué)生基本上看不到白色絮狀沉淀。本文通過以下兩種方法對氫氧化亞鐵制備的實驗進(jìn)行改進(jìn)，均獲得較好的效果。 |

| 正文翻譯： 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. 感覺中文有些詞可以完全不翻譯，而且英語單詞不宜重復(fù)過多！ |
