Azeotropes

A binary solution with strong negative deviations from Raoult's Law will have a maximum-boiling azeotrope, and either of the two components can be obtained by repeated distillation.

If the solution exhibits positive deviations from Raoult's Law, on the other hand, the azeotrope will be minimum-boiling, and distillation will drive the composition of the distillate towards the azeotrope.

The series of videos about binary solutions that you propose is very underrated. I'm glad I've found these videos as there are very few chemistry videos about this particular chapter in my native language. Thanks very much

Im a 12th grader and literally loved the content sir....very relevant to IIT JEE exam which I'm preparing for.
my teacher didn't explained us about the difference in distillation process of the 2 types of azesotropes... Huge respect and ❤️ from 🇮🇳IN

Fantastic video, I was on the edge of understanding azeotropes and the methodical steps you put out in this video just allowed me to fully grasp it. Thank you!

[sohamadak]

That was so well explained, I had a doubt in this topic for so long

[SujalRajput]

Sir you really have a gift of teaching such hard concepts, with ease. I hope you get more recognition. Your explanation was to concise and easy to follow. Just what i want.

[purplepantedits]

The topic was really shallow in my text book, this help me a lot. Thank you.

[jazmingarcia]

Excellent video. Couldn’t understand this for months and you explained it very clearly. Thanks:)

[omchavan]

Thanks a Lot Sir your teaching is really good I was able to get all the concept and I think because of you now I might be able to Top Physical Chemistry Test.

[tranhoangthanhtruc]

thank you so much for your clear explanation! I really appreciate your lesson!

[vaibhav]

Thank you so much ❤
I was really confused of azeotropes before ...
I am preparing for IIT-JEE 🇮🇳

I am now learning about Azeotrope because I accidentally made one mixing my super hot tap water with 91% ISO to clean some bong parts (the pure iso melts the plastic cup I use) and it started to boil and it scared me lol, I set it down and backed out of the room because normally boiling when mixing chemicals and you don't know why is a BAD sign haha. I love science

[survivinginbim]

Wonderfully explained, I understand so much better. I have a question If a nitric acid and water mixture shows a negative deviation from Raoult's law, why is only 63% nitric acid obtained and not 100%?

[oleksiyi.]

Good refresher, thank you for contributing!

[OgeOliver]

I finally understand what this Azeotropes are about.

[ngjackson]

Thank you for the short yet illuminating lecture on azeotropes. Could I just ask why would there be a preference between min./max. boiling azeotrope for separation? 

Wouldn't the high purity product just come from the distillate for max. boiling azeotropes and bottoms for min. boiling azeotropes?

[Waffen_SS-qc]

Can you relate the temperature-composition diagram to the actual distillation column in the oil refinery industry. The separation of gasoline from crude oil and the temperature on the top of the distillation column is cooler than the bottom. Thanks. 😊

[ahmedabdinur]

This helped me really.
Thank you very much.

[abidurrahman]

Thank you very much. This was very helpful

[MANOJKUMAR-lhog]

wow very nice explanation. thanku so much sir

[izyhew]

Thankss for the explaination sir !
Sir i have one question, how to determine the first drop of vapour and the last drop of liquid for minimum azeotrope graph?
