Sodium bifluoride is the inorganic compound with the formula NaHF2. It is a salt of sodium cation (Na+) and bifluoride anion (HF2−). It is a white, water-soluble solid that decomposes upon heating .〔Perry, Dale L.; Handbook of Inorganic Compounds; CRC Press (2011); page 381; ()〕 Sodium bifluoride is non-flammable, hygroscopic, and has a pungent smell.〔 Sodium bifluoride has a number of applications in industry. ==Reactions== Sodium bifluoride dissociates to hydrofluoric acid and sodium fluoride: :NaHF2 HF + NaF The reverse of this reaction is employed to remove HF from elemental fluorine (F2) produced by electrolysis. This equilibrium is manifested when the salt is dissolved and when the solid is heated. Characteristic of other bifluorides, it reacts with acids to give HF. Illustrative is its reaction with bisulfate to form sodium sulfate and hydrogen fluoride. Strong bases deprotonate bilfluoride. For example calcium hydroxide gives calcium fluoride. 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「Sodium bifluoride」の詳細全文を読む スポンサード リンク
