Video Summary:
This video explains mechanism of action of surfactants i.e. how surfactants reduce surface tension. The fundamental concept is very simple. The basic cause of surface tension is downward pull on the surface water molecules. Surfactants molecules are made in such a way that there is no downward pull on them. Also they decrease the downward pull on nearby water molecules. This results in reduced surface tension.

There is no dedicated video but videos "Phospholipids in water" and "membrane proteins" might help. Search for these title in our channel. I hope that gives you some idea.

Sir... Can you expand the concept of density?... As of how it reduces density of water molecules on surface
@NonstopNeuron
2 жыл бұрын
It's very simple. But as you have asked, I will elaborate. Density here is number of water molecules per let's say square mili meter of the surface. Without surfactants it's only water molecules on the surface. So their density is high. However, when surfactants are there, they displace water molecules. Or in simple words, the same surface area is shared by both, surfactants and water molecules. So obviously less number of water. molecules would be there is the same square mili meter of the surface. It's like let's say 100 homes are there in 1 square kilometre of a city and each one is occupied by a doctor. So we have 100 doctors is 1 square kilometre. But then 10 lawyers came and replaced 10 doctors from 10 homes. So now we have only 90 doctors per square kilometre. I hope it's clear now.

I still don't get it ☹️☹️☹️ Why surface tension increase collapsing pressure when there is a pull downwards and in-between them on surface.... When molecules are pulled downwards they should reduce collapsing pressure????
@NonstopNeuron
Жыл бұрын
I understand your confusion. Think step by step. Downward pull tends to reduce surface area. Now image what would happen if surface area decreases... Collapse.! I hope this helps.
@NonstopNeuron

Or forget downward pull. You understand that there is tension between molecules on the surface right!. Now just think what all these tense molecules would do? They will try to come closer. And as the do so, there is collapse.
