Although this document deals with fluorine the gas or pressurized liquid, there is a possibility that these other chemicals will come into play in the patient’s treatment plan. Aqueous hydrogen fluoride (hydrofluoric acid) is used to etch glass and to analyze minerals for their silicon content. Oxygen difluoride was first reported in 1929; it was obtained by the electrolysis of molten potassium fluoride and hydrofluoric acid containing small quantities of water. (a) Write an equation for the reaction of solid silicon dioxide with hydrofluoric acid to yield gaseous silicon tetrafluoride and liquid water. The reaction of fluorine with ammonia produces dinitrogen tetrafluoride and hydrofluoric acid. This decreases the availability of free fluorine atoms for oxygen atoms to react with and destroy ozone molecules.
