About Hydrofluoric Acid 48% Solution (48-51%), ACS Reagent Grade

Hydrofluoric Acid, is the aqueous solution of Hydrogen Fluoride. Fluorine is the only halogen that does not form a strong acid, due in part to the electronegativity and small size of the fluorine atom which results in stronger bond formation between fluorine and hydrogen. Lab Alley’s Hydrofluoric Acid, 48% Solution contains 40-60% by weight of Hydrogen Fluoride in 40-60% by weight of Water. The ACS Grade is generally equivalent to the Reagent Grade and is acceptable for use in analytical applications and research laboratories. 

Common Uses and Applications

  • Synthesis of fluorine-containing compounds (e.g. Teflon, Prozac, freon)
  • Glass etching
  • Cleaning agent
  • Dissolving rock samples for analysis
  • Oil refining
  • Laboratory reagent
