Friends today we will see a very interesting chemistry experiment – an Oxidation Experiment. I have a potato which is a tuber and another rhizome called Colocasia or Taro Root. I also have a beaker with the purplish solution of Potassium Permanganate.
I cut a bit of Taro Root and boiled it in water for 10-minutes. Then I took a sample of that mixture. Similarly, I cut a piece of potato and boiled it in water for 10-minutes. I also took a sample of that mixture. Now we will see how these mixtures react with Potassium Permanganate solution.
On my right is the extract of Colocasia – boiled and filtered. Similarly on my left is the extract of potato – again boiled and filtered. Now I will add Potassium Permanganate solution to both extracts. After a while you will be surprised to see that the potato extract becomes transparent like water, whereas the Colocasia extract remains purple – indicating the presence of Potassium Permanganate. The potato extract becomes like water. This is a very good example of OXIDATION REACTION.
