fluorescent dye
— Navneord
– Engelsk
～ a yellow dye that is visible even when highly diluted; used as an absorption indicator when silver nitrate solution is added to sodium chloride in order to precipitate silver chloride (turns pink when no chloride ions are left in solution and negative fluorescein ions are then absorbed)

– Engelsk
～ subject to fluoridation; treat with fluoride; "fluoridized water"; "fluoridize the teeth of children"
fluoridation
— Navneord
– Engelsk
～ the addition of a fluoride to the water supply (to prevent dental decay)
fluoride
— Navneord
– Engelsk
～ a salt of hydrofluoric acid
fluoridisation
