Product Description

                                                                      Ammonium Fluoride
1.Character

     It is a white crystal with corrosive to skin and toxic. It is soluble in water and methanol, slightly soluble in ethanol, insoluble in propanone and liquid ammonia. When it is in hot water decomposition will occur to release ammonia and ammonium bifluoride.It is white or colorless transparent orthorhombic crystal at room temperature, with a slightly sour taste. It is easily deliquescent when heated or in hot water, and decomposes into ammonia and hydrogen fluoride. Decomposed in hot water, the aqueous solution is strongly acidic. It is obtained by neutralizing anhydrous hydrofluoric acid with liquid ammonia.
