Potassium Fluoride is considered to be the second most important source of fluoride ion in chemistry applications. Having molecular formula KF, it shows molar mass of 58.0967 g/mol in anhydrous form with colorless appearance. This compound is also used for conversion of chlorocarbons into fluorocarbons. It has colorless crystalline appearance with density of 2.48 g/cm3 having boiling & melting points of 1502 and 858 degrees Celsius respectively. Potassium Fluoride is water soluble in nature and can be industrially prepared by dissolving potassium carbonate into hydrofluoric acid. It is an alkali halide that can be naturally found as mineral carb bite.
