It consists of three potassium cations and a central hexacyanometallate with ()3− anion. It is a yellow, air-stable, paramagnetic solid. It is not stable at higher temperatures, forming chromium(III) hydroxide precipitate. The salt is prepared by treating chromium trioxide ,dissolved in concentrated hydrochloric acid, with ethanol in a redox reaction. Following the solution is evaporated to dryness. The residue is dissolved in a boiling solution of KCN. The evaporation is repeated, but not till dryness. The concentrated solution is left in the cold to sulphur. The Cr(II) derivative is unusual and has been little studied. == References == 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 hexacyanochromate(III)」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.
