Potassium bifluoride
| Quote: |
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 products
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 hydrofluoric acid:
2 HF + KOH → KHF2 + H2O

What container is suitable for evoporation step?
Anyone made potassium bifluoride?
