Potassium Bifluoride (KHF₂)

Synonyms: Potassium Hydrogen Fluoride
CAS No.: 7789-29-9
Molecular Formula: KHF₂
Molecular Weight: 78.10 g/mol

Potassium Bifluoride is a colorless, tetragonal or cubic crystalline solid with a slightly acidic odor. It has a relative density of 2.37 and a melting point of 225°C. Potassium bifluoride is highly soluble in water but insoluble in alcohol. Its aqueous solution exhibits acidity. While stable in dry air, it decomposes in humid air, releasing hydrogen fluoride (HF). When heated to 310°C, it releases HF gas, with a steam pressure of 0.10325 Mpa (1 atm) at 400°C. The activity of fused potassium bifluoride is greater than that of potassium fluoride, but it is toxic and caustic.

Ammonium hydrogen fluoride is a compound formed from ammonium fluoride and hydrogen fluoride, with hydrogen fluoride molecules occupying spaces in the ammonium fluoride crystal lattice. It is the major constituent in glass-etching fluid (though sometimes replaced by potassium hydrogen fluoride), etching occurring due to the fluorination of silicon:
SiO_{2 (s)}+ 4[NH₄][HF₂] _(AG) SiF_{4 (l)} + 4[NH₄]F _(AG) + 2H₂O _(l)
Our huge range of chemical compound is extensively used in anodizing of aluminum, wood preservative and glass cleaning, etching & pickling. Available at competitive prices, our offered Ammonium Bifluoride is well appreciated in the market for its salient properties such as purity, longer shelf life and accurate composition.
