The Reaction of Sulfur and Fluorine Gas

In this video from Periodic Videos we look at the reaction of Fluorine Gas and Sulfur.

NOTE FROM THE PROFESSOR: This is a very violent reaction so many things may be going on. In the molecular structure of solid sulfur, one finds S8 rings. At the simplest level, these react to form SF6; S8 + 48F2 → 8SF6. However, this reaction is involves a jet of F2 gas so there may not be enough fluorine and some SF4 may be formed. SF4 can react violently with water in the air to form SO2 and HF.
