翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Old Nassau reaction ： ウィキペディア英語版 Old Nassau reaction The Old Nassau reaction or Halloween reaction is a chemical clock reaction in which a clear solution turns orange and then black. This reaction was discovered by two undergraduate students at Princeton University researching the inhibition of the iodine clock reaction (or Landolt reaction) by Hg2+, resulting in the formation of orange HgI2. Orange and black are the school colors of Princeton University, and "Old Nassau" is a nickname for Princeton, named for its historic administration building, Nassau Hall. ==Chemical equation== The reactions involved are as follows: #Na2S2O5 + H2O → 2 NaHSO3 #IO3− + 3 HSO3− → I− + 3 SO42− + 3 H+ This reaction reduces iodate ions to iodide ions. #Hg2+ + 2 I− → HgI2 Orange mercury iodide solid is precipitated until the mercury is used up. #IO3− + 5 I− + 6 H+ → 3 I2 + 3 H2O The excess I− and IO3− undergo the iodide-iodate reaction #I2 + starch → a blue/black complex A blue/black starch-iodine complex is formed. 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「Old Nassau reaction」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.
