  • 1. Working with sulphur By Louis Gruebner&Sam Quilter
  • 2. S 8 Molecule Solid sulphur is a yellow powder with a low melting and boiling point. This tells us that it is likely to be held together by relatively weak Van der Waals forces.
  • 3. Liquid Sulphur When sulphur melts at 113°C it becomes a runny yellow liquid. This is because the weak Van der Waals bonds break apart and the molecule becomes more mobile.
  • 4. More liquid sulphur When heated further the yellow liquid turns dark red and becomes viscous.
  • 5. Solid red sulphur When in this state the molecules have reformed into long polymer molecules. It becomes solid because the Van der Waals forces are stronger due to the size of the molecules.
  • 6. Black liquid sulphur This is formed when the bonds break again and the Van der Waals forces get weaker. This viscous liquid when poured into water will become plastic sulphur.
  • 7. Plastic sulphur A dark rubbery substance formed when black liquid sulphur is exposed to cold water.
