It is known to produce a blood red color in solution. This is used as a test for Fe3+ in the laboratory. Fe3+ reacts with thiocyanate to give a series of intensely red colored compounds which remain in the solution and does not undergo any reaction after the formation of the stable octahedral structure. In high concentration of SCN− the compound is fairly octahedral with six thiocyanate ligands bonded to iron atom. Thiocyanatoiron forms a pentahydrate. Thiocyanatoiron must be stored in an acidic solution to prevent the formation of FeOH2+ ions. The excess H+ ions in the acidic solution prevent Fe3+ from engaging in side reactions. Thiocyanatoiron decomposes with exposure to light. The thiocyanatoiron ion is usually formed through an equilibrium reaction: :Fe3+(aq) + SCN−(aq) ↔ ()2+(aq) == Chemical properties == 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「Thiocyanatoiron」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.
