Sodium Bi Fluoride has white free flowing powder appearance with high solubility in water. As an inorganic compound with formula NaHF2, its a salt of sodium cation (Na+) and bifluoride anion (HF2-) that decomposes upon heating. Being non-flammable as well as having pungent smell, it finds applications as cleaning agents and laundry sours. Apart from this, it is also used in process used for plating metal cans. Further, this compound also supports enhancing corrosion resistance of some magnesium alloys.
