Procedure: Ethene is bubbled into a test tube containing acidified potassium permanganate.
Observation: The purple colour of the solution disappears.
Explanation: Ethene reduces the potassium permanganate.
The permanganate ion is reduced to Manganese (II) ion and water.
Note: The net effect of the above reaction is the addition of two –OH groups to the double bond forming ethan-1, 2-dio(ethylene glycol).
In cold countries ethylene glycol is used as an antifreeze in car radiators.
