A crystalline ionic solid with a brown color, it is the potassium salt of tetraperoxochromate(V), one of the few examples of chromium in the +5 oxidation state. ==Preparation== Potassium peroxochromate is prepared by reacting hydrogen peroxide with potassium chromate at low temperatures: : 2 + 8 → 2 + 8 The intermediate tetraperoxochromate(VI) is reduced by hydrogen peroxide, forming tetraperoxochromate(V):〔(【引用サイトリンク】 Preparation, Structure and Vibrational Spectroscopy of Tetraperoxo Complexes of CrV+, VV+, NbV+ and TaV+ )〕〔 〕 : 2 + 2 + → 2 + 2 + Thus, the overall reaction is: :2 + 9 + 2 → 2 + 10 + The compound decomposes spontaneously at higher temperatures. 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「Potassium tetraperoxochromate(V)」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.
