Sodium bifluoride is the inorganic compound with the formula NaHF2. It is a salt of sodium cation (Na+) and bifluoride anion (HF2−). It is a white, water-soluble solid that decomposes upon heating . Sodium bifluoride is non-flammable, hygroscopic, and has a pungent smell.Sodium bifluoride has a number of applications in industry.
Production
Sodium bifluoride is produced by neutralizing waste hydrogen fluoride, which results from the production of superphosphate fertilizers. Typical bases are sodium carbonate and sodium hydroxide. The process occurs in two steps, illustrated with the hydroxide:
Sodium bifluoride reacts with water or moist skin to produce hydrofluoric acid. It also gives off hydrofluoric acid and hydrogen gas when it is heated to a gaseous state. The chemical can decompose upon contact with strong acids, strong bases, metal, water, or glass. Sodium bifluoride also engages in violent reactions with chromyl chloride, nitric acid, red phosphorus, sodium peroxide, diethyl sulfoxide, and diethylzinc.
Applications
The main role of sodium bifluoride is as a precursor to sodium fluoride, millions of tons of which are produced annually.
Cleaning agents and laundry sours
The compound also has applications in cleaning, capitalizing on the affinity of fluoride for iron and silicon oxides. For example, formulations of sodium bifluoride are used for cleaning brick, stone, ceramics, and masonry. It is also used to etch glass. Another application of sodium bifluoride is in the chemical industry. Other applications of the compound involve the galvanization of baths and pest control. Sodium bifluoride's biological applications include the preservation of zoological and anatomical samples.
Other applications of sodium bifluoride include neutralizers of laundry-rinse.
Other uses
Sodium bifluoride has a role in the process that is used to plate metal cans.Sodium bifluoride also aids in the precipitation of calcium ions during the process of nickel electroplating. The compound also aids in increasing the corrosion of resistance of some magnesium alloys
