Why does the color of potassium permanganate not disappear when excess of ethanol is added to it?
The color of potassium permanganate does not disappear when excess ethanol is added because ethanol is unable to fully reduce the permanganate ion (MnO4-) to colorless manganese dioxide (MnO2). Ethanol is a weak reducing agent and is not capable of completely reducing the permanganate ion in this reaction. Additionally, the reaction between potassium permanganate and ethanol is not stoichiometric, meaning that there is an excess of one of the reactants, which can also contribute to the color persisting.

This phenomenon is known as selective absorption or subtractive color mixing.
