Activity 4.5 Take about 3 mL of ethanol in a test tube and warm itgently in a water bath.Add a 5% solution of alkaline potassium permanganatedrop by drop to this solution.Does the colour of potassium permanganate persist whenit is added initially?Why does the colour of potassium permanganate notdisappear when excess is added?

Answer» MARK IT AS BRAINLIEST Initially color disappears because colored permanganate ions of potassium permanganate are consumed to oxidise ethanol. 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.HOPE IT HELPS ❤
