'

Ammonium acid fluoride, also known as ammonium bifluoride, is an inorganic compound with the formula NH4HF2. It is produced by the reaction of hydrofluoric acid and aqueous ammonia. It is a white solid with a faint odor of ammonia and is soluble in water, alcohol, and ether.

Ammonium acid fluoride is used in many industrial applications, including the production of aluminum, glass, and ceramics. It is also used in some detergents to remove mineral deposits from glass and metal surfaces. In laboratories, it is used as an etchant for some metals, as well as for cleaning and polishing samples.

Ammonium acid fluoride is harmful if inhaled or ingested, and contact with the skin should be avoided. If these precautions are not taken, it can cause skin irritation, burning, and tissue damage. Long-term exposure to high concentrations can cause severe respiratory irritation. The use of protective equipment, such as gloves and a respirator, is recommended.
