It was first reported by Winkler in 1886. ==Properties and preparation== Germanium(II) hydroxide is formed as a white or yellow precipitate when base is added to solutions containing GeII produced for example by the reduction of an acid solution of GeO2, germanium dioxide with H2PO3, hypophosphorous acid or alternatively by hydrolysis of GeCl2 The initial precipitate, which has no definite stoichiometry, can be represented by GeO.xH2O, Ge(OH)2.xH2O or loosely Ge(OH)2 and is only slightly soluble in water or alkali and is not appreciably soluble in perchloric acid, HClO4.〔 It is soluble in hydrochloric acid,HCl.〔 On digestion with sodium hydroxide, NaOH it yields a brown insoluble compound which after drying in vacuo forms a brown pyrophoric substance with the approximate stoichiometry of (HGe)2O3. On the basis of the infrared spectrum (HGe)2O3 may contain a germanium hydrogen bond, Ge-H.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Germanium(II) hydroxide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
