Cleansing action of soap | Chemical reactions | Chemistry
This video explains why soap is used to remove oil and grease.
We know that oil and water do not mix. So, water alone cannot remove oil stains. In this video we see that even after the 2 liquids are mixed together vigorously in a test tube they separate, with the oil lying above the water. However, when in addition to water and oil, some liquid soap is added and the mixture is vigorously shaken, the separation of oil and water is not seen. This is because soap has both hydrophilic and hydrophobic ends. The hydrophilic end combines with water and the hydrophobic end with the oil allowing the formation of an emulsion. This property of soap allows oil to combine with it and so soapy water can remove oil stains.

its a great project
VII Chemistry Project: 1. Study the neutralisation reaction between vinegar and baking soda (Make ppt (5 slides) related to the above topic, type your observation in 4th slide and insert your project photos in 5th slide) tabulate your results) - should send this project in Assignment format with your project photo
Good explanation
Very NYC sir u should make more practical vedios on chemistry plz
Thanks a lot 🙏 🙏🙏🙏🙏🙏
wow i didn't know that that's so cool
nice
Nice
Can I use this practical contents to make video in my language..?
His hand is shaking terribly
Sri please put the video
U are mad
Nice
