Question

on adding the pink coloured solution of potassium permanganate to ethanol, the pink colour disappears in the beginning
​

Answer 1

Explanation:

When you add the pink coloured solution of potassium permanganate to ethanol, the pink colour disappears in the beginning, because potassium permanganate is used up in the oxidation reaction.

Answer 2

Answer:

The answer to the question -"on adding the pink coloured solution of potassium permanganate to ethanol, the pink colour disappears in the beginning"is-

This happens as potassium permanganate is used up in the oxidation reaction.

Explanation:

When we add the pink coloured solution of potassium permanganate to ethanol, the pink colour disappears in the beginning. The color of  potassium permanganate  that is, KMnO4  disappears as KmNO4 acts as oxidising agent. It oxidises oxalic acid to CO2 and  therefore, it changes to Mn2+ ion which is colourless ,this happens as potassium permanganate is used up in the oxidation reaction.

Without oxidizing reagents , KMnO4 is  pink in solution. When potassium permanganate reacts with ethanol, it releases nascent oxygen which is an atom of oxygen  and therefore convert  ethanol to acetic acid. In the starting, colour disappears because potassium permanganate is consumed to oxidise ethanol.

The permanent pink colour becomes Colourless at end point as KMnO4 acts as an indicator  where the permanganate ions are  deep purple in colour.

In this redox titration, MnO4– is reduced to colourless magnesium ions (Mn2+) in the last drop of permanganate  ,which gives a light pink colour on reaching the endpoint.
