Ammonium bifluoride | F2H5N | CID 14935
Commercial ammonium bifluoride, which usually contains 1% NH4F, is made by gas phase reactions of one mole of anhydrous ammonia with two moles of anhydrous hydrogen fluoride; the melt that forms is flaked on a cooled drum. Kirk-Othmer Encyclopedia of Chemical Technology. 4th ed. Volumes 1: New York, NY.
Hydrogen halides as acids
The hydrogen halides are colourless gases at room temperature, producing steamy fumes in moist air. Hydrogen fluoride has an abnormally high boiling point for the size of the molecule (293 K or 20°C), and could condense to a liquid on a cool day. Hydrogen fluoride's boiling point is higher than you might expect because it forms hydrogen bonds.
