Warning: This experiment deals with corrosive substances and toxic fumes. Work outside or in a fume hood.
You will need:
Sulfur chloride mixture
The sulfur chloride mixture created in a previous experiment should be orange or red. Add some sulfur to it when warm. The sulfur should dissolve and react with the red sulfur dichloride to make yellow disulfur dichloride. This sulfur chloride is more stable. Disulfur dichloride dissolves sulfur as well. Add disulfur dichloride to water. A yellow solid is formed, along with release of sulfur dioxide gas and hydrogen chloride fumes.
