翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Bulk electrolysis ： ウィキペディア英語版 Bulk electrolysis Bulk electrolysis is also known as ''potentiostatic coulometry'' or ''controlled potential coulometry''. The experiment is a form of coulometry which generally employs a three electrode system controlled by a potentiostat. In the experiment the working electrode is held at a constant potential (volts) and current (amps) is monitored over time (seconds). In a properly run experiment an analyte is quantitatively converted from its original oxidation state to a new oxidation state, either reduced or oxidized. As the substrate is consumed, the current also decreases, approaching zero when the conversion nears completion. The results of a ''bulk electrolysis'' are visually displayed as the total coulombs passed (total electric charge) plotted against time in seconds, even through the experiment measures electric current (amps) over time. This is done to show that the experiment is approaching an expected total number of coulombs. == Fundamental relationships and applications == The sample mass, molecular mass, number of electrons in the electrode reaction, and number of electrons passed during the experiment are all related by Faraday's laws of electrolysis. It follows that, if three of the values are known, then the fourth can be calculated. The bulk electrolysis can also be useful for synthetic purposes if the product of the electrolysis can be isolated. This is most convenient when the product is neutral and can be isolated from the electrolyte solution through extraction or when the product plates out on the electrode or precipitates in another fashion. Even if the product can not be isolated, other analytical techniques can be performed on the solution including NMR, EPR, UV-Vis, FTIR, among other techniques depending on the specific situation. In specially designed cells the solution can be actively monitored during the experiment. 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「Bulk electrolysis」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.
