Lithium hexafluoroarsenate is an inorganic chemical compound with the chemical formula LiAsF6.[1][2][3]
Synthesis
[edit]Reaction of arsenic pentafluoride and lithium fluoride in liquid hydrogen fluoride:
- LiF + AsF5 → LiAsF6
Physical properties
[edit]Lithium hexafluoroarsenate forms crystals. It is well-soluble both in water and organic solvents.[4][5] It forms a crystallohydrate of the composition Li[AsF6]•H2O. Its crystals are of rhombic system.[6]
Chemical properties
[edit]Strong oxidizing and reducing agents as well as strong acids and bases cause violent reactions with lithium hexafluoroarsenate. The decomposition produces hydrogen fluoride, arsenic oxides, and lithium oxide.
Uses
