Question

. 3 mL of ethanol is taken in a test tube and warmed gently in a water bath. A 5% solution of alkaline potassium permanganate is added first drop by drop to this solution, then in excess. (i) How is 5% solution of KMnO4 prepared? (ii) State the role of alkaline potassium permanganate in this reaction. What happens on adding it in excess? [3] (iii) Write chemical equation of this reaction [3]​

Answer 1

Answer:

the ans is

Explanation:

5 g potassium permanganate is dissolved in 100 ml of water for preparing a 5 % solution of KMnO4. (ii) Alkaline potassium permanganate is adding oxygen to alcohol and converting that to an acid. Hence, it is acting as an oxidising agent.
