Explanation:
Three drops of the compound to be tested are dissolved in 2 ml of water or aqueous ethanol.
2% KMnO4 solution (a purple solution) is added Dropwise and the solution is shaken.

If the purple color of the KMnO4 changes to brown in this reaction, it states that the reaction obtained is
A POSITIVE REACTION. That means the purple color of KMnO4 solution disappears and a precipitate of MnO2 is formed.
