Oxygen difluoride reacts very slowly with water to form hydrofluoric acid: It can oxidize sulphur dioxide to sulfur trioxide and elemental fluorine: However, in the presence of UV radiation the products are sulfuryl fluoride, SO2F2, and pyrosulfuryl fluoride, S2O5F2: Oxygen difluoride is considered an unsafe gas due to its oxidizing properties. Hydrofluoric acid produced by the hydrolysis of OF2 with water is highly corrosive and toxic, capable of causing necrosis, leaching calcium from the bones and cardiovascular damage, among a host of other insidious effects.
