- Fill one third of the test tube or breaker with potassium dichromate solution.
- Add some sulfuric acid to the potassium dichromate solution.
- Pour some diethyl ether on the top of the mixture. If you have added it carefully it should float on the top of the mixture since it is immiscible with water.
- Finally put a few drops of hydrogen peroxide to the vessel.
- A violent reaction between the components takes place. The organic layer turns blue. The appearance of the third dark layer on a border between organic and inorganic phases is observed. A large amount of gas is released.
