Why does the colour of potassium permanganate not disappear when

Table of Contents • • • • • • • What happens when potassium permanganate reacts with ethanol? (a) When ethanol is oxidised with alkaline potassium permanganate (or acidified potassium dichromate), it gets oxidised to form ethanoic acid. Why does the colour of potassium permanganate not disappear when added to ethanol? Explanation: Initially colour disappears because colouredpermanganate ions of potassium permanganate are consumed to oxidiseethanol. When excess is added colour does not change because there is nomore alcohol left and hence there is noreaction. How does potassium permanganate react with alcohol? Potassium permanganate (KMnO4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols. Under controlled conditions, KMnO4 oxidizes primary alcohols to carboxylic acids very efficiently. What colour does potassium permanganate change to? purple Complete step by step answer: Given that potassium permanganate changes the colour from purple to colourless. The chemical formula of potassium permanganate is KMnO4 . What happen when 5% alkaline potassium permanganate solution is added to warm ethanol? (a) On adding 5% alkaline potassium permanganate solution drop by drop to some warm ethanol, we would observe that the purple color of potassium permanganate starts disappearing. The product formed by this process is ethanoic acid that can turn blue litmus red. Does the colour of ...

When excess is added colour does not change because there is nomore alcohol left and hence there is noreaction. Why does the color of potassium permanganate disappear? The colour of KMnO4 disappears when oxalic acid is added to its solution in an acidic medium. What happens when potassium permanganate is added to ethanol? Alkaline potassium permanganate is a very strong oxidising agent. Thus, potassium permanganate adds oxygen to the ethanol and converts ethanol to an acid. The acid formed in the reaction is acetic acid. Which colour of potassium permanganate vanishes when reacts with ethanol? Due to the acidic environment of ethanoic acid, the dark purple colour of \[\]is added to a solution of ethanol and warmed a little, the colour of potassium permanganate disappears. Does the colour of potassium permanganate persist when it is added initially? Initially color disappears because colored permanganate ions of potassium permanganate are consumed to oxidise ethanol. When excess is added color does not change because there is no more alcohol left and hence there is no reaction. Why is potassium permanganate purple in colour? Potassium permanganate(KMnO4) is colored because it absorbs light in the visible range of the electromagnetic...

Is it possible for potassium permanganate to have color change (in a titration) from colorless to pink? If so, then in what circumstances (particularly for a titration)? I have been always been taught that color change for potassium permanganate is purple/pink to colorless. I have scoured the whole internet searching for an example and I couldn't find one. The problem is a question in a recent A level paper which asked about the color change of $\ce$ solution. The answer was colorless to pink. The examiner report further mentioned that many students wrote purple/pink to colorless, however it was marked incorrect. Can someone explain the ambiguity here? An aqueous solution of potassium permanganate, $\ce$, your analyte solution remains purple. $\begingroup$ @FaiqRaees During the titration, $\ce$ will now yield the persistent purple colouration. $\endgroup$
