It is a purple, water-soluble solid. ==Synthesis and reactions== The title compound is prepared by oxidation of a solution of cobalt(II) salts in aqueous ammonia. :2 CoBr2 + 8 NH3 + 2 NH4Br + H2O2 → 2 ()Br2 + 2 H2O It was first reported in the 1870s, before the structure or even formulae were understood for such complexes. This early work showed that only two thirds of the bromide groups were exchangeable with other anions such as nitrate and dithionate. The complex undergoes aquation, meaning that bromide is displaced by water: :()Br2 + H2O → ()Br3 This process is catalyzed by platinum. 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「Bromopentaamminecobalt(III) bromide」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.
