You are very welcome Shreyash. You are working really hard in this lockdown 👏. Well done ! Stay motivated and encourage your friends and classmates to do the same. Adding some new videos on Organic compounds and their study. Do stay tuned. Happy studying : )
😀😀😀 That's a very creative comment Opio George. I am so glad to have been of help 🙏. Hope you did share the channel with your friends as well. Wish you the very best.

mam how did the composition is changing, as when we heat that amount ,that amount is again becoming liquid so how can the composition change from c1 to c2 and mam my other doubt is what will the state at that common point where azeotrope is forming , liquid or vapour ?
Hello Yash Veer, Happy to answer your queries, let me try my best. 1) When you heat the mixture, both the liquids will evaporate but the one with the higher boiling point( A) will cool and condense faster making it fall back into the mixture, so the vapour is richer in the more volatile liquid. 2) azeotrope is the mixture left behind in the distillation flask once it reaches the point O. So the vapour and liquid both will have azeotropic composition. 3) If you notice, the behaviour of A and B is not ideal. Only in an ideal mixture, one will evaporate the other will not. Here, they show abnormal behaviour. Would encourage you to watch the video on ideal solutions first if you have not done so already. ruclips.net/video/TSlu2LpvPtQ/видео.html Hope this helps.

Hello Khushi, thanks for your interest in the channel. The residue in this case will always be an azeotropic mixture once the solution in the distillation flask reaches that composition. The distillate will however depend on the composition of the original mixture taken for distillation. If it is in between A and the azeotropic mixture then pure A will be obtained as distillate but it you start at any composition between B and the azeotropic mixture point then it is pure B which will be obtained as distillate. Hope this helps to clear your doubt. Please subscribe to the channel as more topics will be added soon.

Is it possible to obtain pure ethanol or pure water by boiling the mixture with their own respective boiling point? For example, I boil the mixture of 80% water and 20% ethanol at 100-degree Celcius, will I get pure water in the distillate?
Jia Cheng Loh- Thanks for your interest. We cannot obtain pure ethanol or water by this method as the composition of the mixture ultimately reaches the azeotropic concentration at which both will boil off together. We cannot achieve a temperature of 100⁰ Celsius for the mixture directly. The temperature will rise by degrees and the azeotrope of alcohol and water boils at 78.2⁰ C which is even below the bpt of pure alcohol (78.4⁰C). Eventually, it is 95.6% Ethanol as distillate and pure water in the distillation flask as residue. Hope this clears your doubt.

Hello Prince, yes the temperature does remain constant during any phase change be it boiling or condensation. its an equilibrium process. Thanks for watching and your interest in the channel. Happy learning : )
Shukriya 🙏 I used the Google translator to understand your comment but you Thank you also means so much to me🙏. Hope you are subscribed to the channel and will share it with friends too. Let us reach out to millions who want to learn. Best wishes
Hello Hugo It's like two strangers walking on their path and start chatting with each other and they become friends and realise that they have a common goal and decide not to part ways and stay together 😊. The same process happens with these liquids-they have different boiling points but at a certain composition they just decide to stay together and boil together no matter what the temperature! Hope this makes it clearer 😊.
@@PenandPaperChemistry yes I can understand it 😁. But why is it possible to have like a pure component ? Do you need to increase the temperature? (sorry for the English I may don't understand it 😅) I have an exam in 6 days and it's really kind to respond quick 😇
Possible or not possible? Ok i think you want to know how we can get the pure component? We can get the pure component by other methods like fractional crystallisation, vaccum distillation etc depending on the components of the mixture. We can't separate them by fractional distillation. Did i solve your query? Best of luck for the exam
Not at all dear, that's what the channel is all about. 😊. I am so glad you asked because from my experience if you don't clear your doubt you start losing interest in the subject. But was your doubt finally cleared out not? Most welcome to clear doubts in future as well. Let me know how you did in the exams? Best Wishes
Hope you have subscribed to and shared with your friends channel: ruclips.net/user/LearningChemistryisfun as new videos are on their way esp on topics like Thermodynamics and reaction mechanisms.
Ma'am you have cleared all my concepts..A BIG THANK YOU TO YOU MA'AM

And ma'am also tell at C1 only B will boil as A has more boiling point than the temp at C1

answered above as point 3 : )
Thanks mam
mam can a mixture of volatile solvent and non volatile solute form an azeotrope ?
Unfortunately the volume decreases in a mixture of alcohol and water … the rest is a great explanation!!
Great Teacher ...
🙏 Grace of almighty.
While distillation what would we get as residue and distillate??? How can we understand that?
Hello Khushi, thanks for your interest in the channel. The residue in this case will always be an azeotropic mixture once the solution in the distillation flask reaches that composition. The distillate will however depend on the composition of the original mixture taken for distillation. If it is in between A and the azeotropic mixture then pure A will be obtained as distillate but it you start at any composition between B and the azeotropic mixture point then it is pure B which will be obtained as distillate. Hope this helps to clear your doubt.

Mam u said when we heat temperature remains constant but why this don't work when we cool the solution even though phase change is still taking place.
