Oxygen difluoride reacts very slowly with water to form hydrofluoric acid : OF2 ( aq ) + H2O ( l ) → 2 HF ( aq ) + O2 ( g ) Oxygen difluoride oxidizes sulfur dioxide to sulfur trioxide : OF2 + SO2 → SO3 + F2 However , in the presence of UV radiation the products are sulfuryl fluoride , SO 2F 2 , and pyrosulfuryl fluoride , S 2O 5F 2 : OF2 + 2 SO2 → S 2O 5F 2 In Robert L. Forward 's science fiction novel Camelot 30K , oxygen difluoride was used as a biochemical solvent by fictional life forms living in the solar system 's Kuiper belt .
