. Sodium Fluoride
Potassium bifluoride is the
inorganic compound with the formula KHF2.
- This colourless salt consists of the
potassium cation and the bifluoride (HF2-) anion.
- The salt is used in etchant for glass.
- Sodium bifluoride is related
and is also of commercial use as an etchant as well as in cleaning
- KHF2 is very dangerous reagent.
- The aqueous solution of KHF2 is weak acid,
but if it is exposed other acid solution or basic solution, hydrogen
fluoride gas is generated and the gas is very toxic.
- It is a colourless tetragonal
or cubic crystal with slightly acidic smell and relative density of
2.37, mp 225°C.
- It is easy soluble in water, insoluble inalcohol.
- Itsaqueous solution is acidity.
- It is stable in dry air, but decomposes to
release hydrogen fluoride in humid air.
- It gives of HF when heated to
310°C, and the steam pressure of hydrogen fluoride could reach
0.10325Mpa(l atm) at 400°C
- The activity of fused potassium bifluoride
is greater than potassium fluoride
- It is toxic and caustic.
- The salt was
prepared by Edmond Frémy who decomposed it to generate, for the
first time, hydrogen fluoride.
- Potassium bifluoride is
prepared by treating potassium carbonate or potassium hydroxide with
- Potassium Bifluoride is a water insoluble
Potassium source for use in oxygen-sensitive applications, such as
- In extremely low
concentrations (ppm), fluoride compounds are used in health
- Fluoride compounds also have
significant uses in synthetic organic chemistry.
