potassium hydrogen fluoride usage and synthesis

chemical properties	white to light grey crystals or crystalline powder
general description	colorless crystals, corrosive to tissues, etches glass.
air & water reactions	water soluble giving strongly acidic solutions.
reactivity profile	acidic salts, such as potassium hydrogen fluoride, are generally soluble in water. the resulting solutions contain moderate concentrations of hydrogen ions and have ph's of less than 7.0. they react as acids to neutralize bases. these neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. they usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
health hazard	toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. contact with molten substance may cause severe burns to skin and eyes. avoid any skin contact. effects of contact or inhalation may be delayed. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard	non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). contact with metals may evolve flammable hydrogen gas. containers may explode when heated.
