Answer:
The KMnO4 Test
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. Indications of a positive test: The purple color of the KMnO4 solution disappears and a precipitate of MnO2 is formed.
