Warning: Sulfuric acid at these concentrations is slightly corrosive. Be careful when handling. Sulfur dioxide fumes are poisonous. Do not inhale them. Complete this experiment in a well-ventilated area.


You will need:



Hydrogen peroxide, 3% (a greater percentage gives more concentrated sulfuric acid)

Glass container

Aluminium foil


Shape the aluminium foil into a tray. Fill it with sulfur. Ignite the sulfur by heating the tray over a flame. Place it in the container and close the lid. The jar will fill with sulfur dioxide and sulfur fumes. Open the jar, remove the tray, and add some hydrogen peroxide. Shake the jar. Reignite the sulfur and repeat the process until all of the sulfur has burnt. Now you have a dilute sulfuric acid solution. If you want it more concentrated, boil it down.
