A Woulf's bottle is fitted with a thistle funnel and a delivery tube. Diluted H2SO4 is run down the funnel so as to cover the iron sulphide placed at bottom of the bottle. When iron sulphide reacts with diluted sulphuric acid, hydrogen sulphide is formed which is collected in the gas jar by upward displacement of air. ==Purification of hydrogen sulphide gas== H2S gas obtained from above may contain hydrogen gas and acid impurities. So it is passed through a suspension of MgO in water which gives magnesium bisulphide. The bisulphide on heating above 60°C gives a steady stream of pure H2S gas. :MgO + 2H2S --> Mg(HS)2 + H2O (magnesium bisulphide) :Mg(HS)2 --> MgS + H2S 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「Hydrogen sulfide sensor」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.
