What is Potassium fluoride?
'''Potassium fluoride''' is a [[chemical compound]]. Its chemical formula is KF. It contains [[potassium]] and [[fluoride]] [[ion]]s. ==Properties== Potassium fluoride is a colorless [[crystalline]] solid. It rarely occurs in the ground. It dissolves easily in water. It can react with glass. [[Hydrofluoric acid]] is more effective at reacting with glass, though. It has to be stored in plastic or platinum containers. ==Preparation== Potassium fluoride is made by reacting [[potassium carbonate]] with hydrofluoric acid. This reaction can make potassium bifluoride. Potassium bifluoride is a mixture of hydrofluoric acid and potassium fluoride. ==Uses== It is used because of its fluoride ion. It can be used to add fluoride ions to some chemical compounds. ==Safety== Potassium fluoride is somewhat toxic. It is corrosive to glass. It can burn when spilled on skin. ==Related pages== *[[Sodium fluoride]] *[[Potassium chloride]] {{chem-stub}} [[Category:Potassium compounds]] [[Category:Fluorine compounds]] {{Fluorine compounds}}
