Friends, today we will see a very interesting chemistry experiment. We will see an oxidation experiment. For this I need a potato which is a tuba and another rhizome which is called as kolakashia or the taro root. I also have a beaker with the published solution of potassium per magnet. Well what I do is I cut a bit of the taro root and boil it in water for 10 minutes. Then I took a sample or an extract of that mixture. So I cut a bit of the taro root, boil it in water for 10 minutes and then took an extract of that. Now similarly I cut a piece of the potato and also boil it in water for 10 minutes. I also took a sample of the extract of the boiled potato. So now you will see how these mixtures react when potassium per magnet solution is added to them. Now this on my right side is the extract from the taro root. And on my left side is the extract of the mixture which I got after boiling potato for about 10 minutes. Now I will add potassium per magnet solution to both the extracts. First I add potassium per magnet to the taro root and then to the potato. After a while I find that the potato extract becomes transparent. It looks almost like water whereas the taro root extract still is perplished which means it contains potassium per magnet. Now this is a very good example of oxidation reaction.
