It's best way of teaching. Really i understand well.

[@KhalifaMAsif]

Thanks a lot

[@bruhhmomentumm]

Finally! a good explaination of CMC. I go to a top 10 med school, and they could not explain it as well as this video

[@KhalifaMAsif]

My Pleasure.. dear

[@umairahmadriyazuddin3286]

Nice Session 👍

[@shahabuddinalvi9073]

Very informative video sir. Very simple explanation

[@talhavahora6765]

Informative....
One can learn easily from here...

[@maratheyamini865]

Outstanding session sir thank you so much sir for preparing such a nice video

Thank you sir

[@amanadleshorts7429]

Nice explanation👌

[@k.m.chavan]

Sir really you are doing all practical clearly. Nicely, I understand it by watching. Thank u so much.although I do it in clg but can't understand. Plz upload more practical video s

[@KhalifaMAsif]

Thanks a lot dear, definitely i will work on other Experiment too.

Thank you sir
I have A question at cmc exactly micelles start to form or above cmc?

[@KhalifaMAsif]

most welcome, I am sorry for late responding.
Micelles starts to form exactly at cmc

[@Music-gt2cm]

Sir pls tell about how to calculate density in calculation

[@KhalifaMAsif]

I will make video on that soon

[@prachikumari-rj5jn]

how to take density

[@KhalifaMAsif]

Usind Density bottle. You have to determine density for every sample to calculate surface tension.
Density=mass/volume

[@devshah1751]

Thank you sir, few question related to surfactants used to separate oil-water emulsions:
1. After the CMC is achieved, how much more surfactant needs to be added for oil to separate from water?
2. After oil is recovered, it will contain our surfactant used, can we separate the oil and surfactant if we want to re-use the oil?
Anyone can please help if they know please?

[@KhalifaMAsif]

Welcome dear;
Surfactant mostly used for stabilization of oil and water system.. though some cationic surfactants can be used for separation but it depends on Charges and Temperature 🌡️.

Ohh, sure sir i will check this!
Thank you very much for the help!!😇😇

Sir, if we have a mix of powder, oil and water
We saw cationic surfactants work well there
Some doubts were there as we have not done practical experiments over this,
The top layer will have oil + surfactant
Middle will have water
Botoom will have powder settled, right sir?
By decantation, we can separate oil and surfactant, but if we want to reuse the oil, can we separate the surfactamt from it?
Like, centrifugation technique will work there?

[@KhalifaMAsif]

@@devshah1751 can you give the name of that surfactant and oil

[@devshah1751]

@@KhalifaMAsif
Oil which is used in rolling mills, like, rollwell 50
Cationic Surfactant-
Mix of cationic surfactants CPC-DTAB-TTAB, as they gave a low CMC value.
