In this experiment, a layer of ethanol is placed on top of concentrated sulfuric acid in a test tube. As Potassium Permanganate is introduced to the test- tube, a vigorous reaction starts. The Potassium Permanganate reacts with the sulfuric acid to give Manganese Heptoxide. Manganese Heptoxide is a very unstable compound that rapidly decomposes into Ozone. A combination of Ozone and Manganese Heptoxide reacts with the Ethanol, and Oxidises it to Ethanal (Acetaldehyde)
