Potassium hexafluoroarsenate is an inorganic chemical compound with the chemical formula KAsF6. [2] [3]
Potassium hexafluoroarsenate can be prepared by direct action of arsenic pentafluoride and potassium fluoride:
Also, it can be synthesized by the action of hydrofluoric acid on arsenic pentafluoride in the presence of potassium perbromate: [4]
Also, potassium hexafluoroarsenate is synthesized by treating arsenic pentachloride and potassium chloride in the presence of hydrofluoric acid:
Potassium hexafluoroarsenate is a white powder with a pungent odor. The compound is stable under normal conditions. The melting point is around 400 °C. The substance is not flammable. It is incompatible with strong oxidizing agents. [5]
Potassium hexafluoroarsenate is toxic when swallowed or inhaled and is hazardous to the environment. The compound is considered carcinogenic. Hazards in the event of fire include hydrogen fluoride, potassium oxide and arsenic oxides. [6]
