Potassium fluoride is prepared by reacting potassium carbonate with hydrofluoric acid. Evaporation of the solution forms crystals of potassium bifluoride. The bifluoride on heating yields potassium fluoride: K 2 CO 3 + 4 HF → 2 KHF 2 + CO 2 ↑ + H 2 O KHF 2 → KF + HF ↑. Platinum or heat resistant plastic containers are often used for ...

If HF alone is electrolyzed, hydrogen forms at the cathode (positive part of the cell) and the fluoride ions remain in solution. After electrolysis, potassium fluoride remains in solution. [35] 2 HF 2 − → H 2 ↑ + F 2 ↑ + 2 F −. The modern version of the process uses steel containers as cathodes, while blocks of carbon are used as anodes.

Potassium hexafluoronickelate(IV) is an inorganic compound with the chemical formula K 2 NiF 6. It can be produced through the reaction of potassium fluoride, nickel dichloride, and fluorine. It reacts violently with water, releasing oxygen. It dissolves in anhydrous hydrogen fluoride to produce a light-red solution.
The mass ratio of the solvent and potassium fluoride is 1.1~2.0 : 0.5~1. When the reaction temperature of 100~160 °C is reached, methyl chloroacetate ClCH 2 CO 2 CH 3 is continuously added in the reactor at a speed of 5~10 kg/min with the mass ratio of methyl chloroacetate and potassium fluoride being 1:0.5～1. The reaction between these ...
