Ammonium fluorides are poisonous and corrosive materials. Neutral ammonium fluoride has the relative molecular mass of 37,04 g/mol. Its sum formula reads NH 4 F. There is colorless, dissolving Kristallnadeln glass-corrosive easily soluble in water very and. Their density amounts to 1.32 g/cm ³. With heating up it disintegrates into NH 3 and HF.
Ammonium hydraulic gene fluoride is well-known also under the name ammonium bifluoride or matte salt. Its sum formula reads: (NH 4) HF 2, its relative molecular mass amounts to 57.05 g/mol. It is colorless, easily soluble addition compound from NH 4 F and HF with a density of 1,5 g/cm ³ and by reaction by ammonia with hydrogen fluoride is manufactured.
