Question

Why does the colour of potassium permanganate not disappear when?

Answer 1

Answer:

ie, an atom of oxygen thus converting the ethanol to acetic acid. Initially colour disappears because coloured permanganate ions of potassium permanganate are consumed to oxidise ethanol. When excess is added colour does not change because there is no more alcohol left and hence there is no reaction.........
