Sulfur Pentafluoride: The Color of Love... and Death
Here's a cute cartoon to brighten your day. Sulfur pentafluoride presumably binds with itself to make disulfur decafluoride, a chemical warfare pulmonary agent similar to your good old friend phosgene. Fun stuff. Disulfur decafluoride eventually decomposes into sulfur hexafluoride (which can be used as a sort of anti-helium in gas density demonstrations) and sulfur tetrafluoride (which reacts with moisture in the air to form sulfurous acid and hydrofluoric acid). Incidentally, while I have no idea about the color of sulfur pentafluoride, I can tell you disulfur decafluoride is colorless and one breath can kill you in a day. It takes a while because its actually the acids produced by the sulfur tetrafluoride reacting with water that likely do you in.
