Experiment No. 25: Preparation of Ethene (without conc. sulfuric acid) & detection with Bayer's test

Experimental Chemistry - 2022-03-30

Ethene is made by dehydrating ethanol, using aluminium oxide as a catalyst. The unsatured bonds of Ethene are detected with a moderately alkaline permanganat solution.
