Outstanding video and explanation! I did a PhD in organic chemistry many years ago and I'm now in my 9th year of secondary teaching, planning an A-level lesson - Wow do I wish your videos were around when I was at Uni!
Hello Dr Louise, is this a possible method to extract organochlorine concentration, Im doing a research for my thesis, and its about occurence of OCPs level of concentration in a river.
@@user-pf4cj7kb5e If you were being consistent with running 4 miles everyday, would you instantly change the routine if a meta analysis told you theres a completely new way of running. Sometimes you have to ignore the "most optimal way" of doing things because it just doesnt work for you. Youre acting like you suddenly become unable to memorize and understand once you do it visually lol. The difference is microscopic.
you are actually amazing man. Like any time I find myself in a pinch and I've lost all hope one of your vids will just pop up out nowhere and save my butt
It baffles me how you're able to put out this incredibly high-quality content so consistently and most channels/networks can't advance past a black screen and 20min of "uhh so umm"
This is exactly what we do at my job to analyze water samples for oil and gas. I work for my state's environmental quality department so this is very relevant.
Incredible video!!!! I'm from Mexico and I didn't find a good video about this topic in Spanish, therefore I had to search a video on English and your video it's perfect
an actually useful tuber, one that teaches and also entertains...90% of tubers tend to just to the latter... also glad to see somany people jumping into such a deep can of spaghetti. another cool dave!!..i dont know of any bad daves!
I am crazy of you profesor uffff I have never seen any profesor who did chemistry easy and impressive. I understand as soon as I start your video .please do not die as a living thing. You are important to us
And I'm finally starting to understand what extraction really is😂😂 you know bcz of this whole quarantine thing we can't do these experiments in lab so your videos are a life savor!!Thank you so much!!
You are one of the best professors I know until now. If I have any questions regarding the chemical field because I am pursuing as a chemical engineering technologist in the 2nd year, how can I reach you ?. Thank you a lots for your effort Profs Dave.
If only I had seen your video sooner! I made so many mistakes during that lab because the paragraph-style instructions were not very helpful🥲 I had no idea how to vent when the text asked me to or why we were adding all the chemicals and solvents for. Thank you for teaching me! It helps me regain hope and my passion for chemistry!
Damn professor Dave... idk how you did it, but you took my absolute most difficult (but favorite) subject of organic chemistry and helped me make sense of it. Those acid/base reactions sure come in handy.
Omg this brings back bad memories. I remember in OG Chem I poured out all the liquid by accident🙃. I still remember my partner begin really upset even tho i ask them to where and they said all of it and by all of it they meant the aqueous layer. Hahah fun times 😅
It sounds like you know what you are doing. I took a zip of some NyQuil, after some minutes I felt like a brick was put on my chest and I started to feel so dam sleepy, but I stayed awake watching Netflix. After a couple of minutes of fighting my sleep I felt like the brick was removed and I no longer felt sleepy and I am here 4:20Am writing this to ask you If there's a way to extract the chemical? In NyQuil that makes us fall to sleep. Great video By the way, berry well explained and detailed... I Wish you would be the one person directing every single video on RUclips. This is my 2nd language for you strangers don't correct me, I didn't listen to my English teacher when i was in school and I'm not listening to you now. But Science I do like so, if you can help me out with this, go ahead and reply.
The substance that makes you sleep is diphenhydramine also active ingredient in Benadryl. No need to extract from NyQuil just buy generic sleep aid pills. Same substance
PD is so cute and cuddly in these vids. But he gets a bit less cuddly in those take-down vids he has done. And rightly so. Just funny to see the duality of man in one of favorite legends of chem. teaching.
In an OC lab course the lab assistant provided a good life hack: if you're unsure which layer is which, just draw a line with a marker where both layers meet. Add a little water: if the level of the seperating line remains in line with your marking, then water is the upper layer. If it is raised, water is at the bottom
Hi Dave, thanks for a great video as always! I just have 2 quick questions. 1. What happens to the anion in the strong acid, chlorine in this case? 2. What is the gas that is produced by the reduction of the alanine? My guess is that both questions can be answered in the same way: the anion is ditched by the proton and forms a gas. Is this correct? If so, should there be a warning to not try this at home due to the dangers of chlorine gas?
It’s a chloride ion and it goes nowhere. It is dissolved in the water along with aniline ion. There is no gas product in this reaction. The pressure build up comes from the volatility of the ether.

@@lienloo1274 how did your thesis go
I'm a visual learner, and these videos are SOOOOOOO helpful! Now I'm not as nervous about messing up in lab!
Concepts like "visual learners" And learning styles in general are unsubstantiated by scientific evidence
@@user-pf4cj7kb5ewas about to comment that
@@user-pf4cj7kb5e yes but things like adhd matter, it just makes things more interesting for you to learn thats all that matters for now

U better not be referring to my boy Organic Chemistry Tutor!! Hes great
@@hamzaha.al-quaid2441 Right 😂😂 Organic chem tutor literally got me through most of college

Whadda ya talkin Abeet?
This is really helping me out with the lab report I forgot I had, thank you!
Another absolute banger by Professor Dave. My 10 page pre-lab outline couldn't explain it worse. Bless
This deserves a lot more attention and likes, it was beyond thorough !!!! Loved it !
This is exactly what we do at my job to analyze water samples for oil and gas. I work for my state's environmental quality department so this is very relevant.
Professor Dave another great video, direct and to the point. Keep up the great work. Cheers!
Incredible video!!!!

Who are you and what did you do with Dave? 🤣🤣 nice new haircut professor!
Lol😂😂

Such a good lecturer. Thanks for helping me increase my MCAT score
WOW! your video is saving me on this report i procrastinated. You are truly the michael jordan of organic chemistry.
Did an extraction for the first time last week - wish I had the video before then. It's perfect!
super helpful rn that im doing an organic chemistry lab online during this pandemic. Thanks for the upload!
Yet another excellent video to help with my orgo lab. Thanks prof Dave!
That was SO helpful for my organic chemistry, thank you!
And I'm finally starting to understand what extraction really is😂😂 you know bcz of this whole quarantine thing we can't do these experiments in lab so your videos are a life savor!!Thank you so much!!
I am searching Indian in comment box and I found you😂😂
So happy to discover this channel. Thanks!

You are doing a service to humanity.
Imagine having a lecture with Dave and actually leaving class understanding the material

You are amazing explaining each and every detail! I will definitely recommend you.
Tank u for this videos. You are amazing. Industrial chemistry student from Saudi Arbia❤❤
In 3:14 won’t the choloroanaline and benzoic acid react since they are both acid and base?
Nope. Organic bases and acids don't react spontaneously. They have a higher energy barrier and always require catalysts to react with each other.
What a bloody legend, absolute gold.
Damn professor Dave... idk how you did it, but you took my absolute most difficult (but favorite) subject of organic chemistry and helped me make sense of it. Those acid/base reactions sure come in handy.
That's so cool and clear. Thank you so much from Russia.
I wish i could like this 10 times omg thank u professor dave!
Dude!!!! You are so smort that my teacher uses your videos for lessons
these are so much better than my lab manual's procedures, ngl
well explained and was so useful ... appreciate your efforts and thanks alot
thank you so much! extraction finally began to make some actual sense 👏
OMG thanks so much this video was incredibly helpful it pretty much cleared what was happening in the lab. WOW
Which grade do you learn these seperation methods of compounds?
prof. dave strikes again!
you are the greatest person ever for explaining chemistry❤️❤️❤️❤️
I'm 10 years out of college and wanted to watch something like this on a whim (dare I say, for fun?). Excellent explanation!
Single-handedly destroyed my chem teacher in explaining this. Thank you!
I'm so pissed.
My professor made this sound way more complicated.
Thanks Dave.
these videos are so helpful, I'm doing my degree at uni and still use these for my chem practicals if I can
Thank you so much! Really helped me to improve my understanding.
Thank you Science Jesus
Thank you so much. Great video very easy to understand.
Literally you make my learning to become easier ,,,,,I appreciate you alot

Your voice is soooo soothing
THANK YOU SO MUCH PROFESSOR DAVE
Oooh! I love your new hairstyle, professor :D And nice video, as always!
Top notch content. Congratulations.!
Thank you so much professor for making this video 😇😄

That was awesome! Thank you! please publish more of these videos!
super helpful. Thanks for the upload!
I literally love you, thank you so much 😭
always check the density! solvent like DCM will be at the bottom.
yes good point! though most organic solvents will be on top

@@DaniFilth87 Awesome hack!
Is this grindr that we talkin bout tops and bottoms? Power bottom BTW :)

You're new haircut 👌
And teaching method... 👌
Thank you for such a great explanation!
I am here learning as an aromatherapy student lol, thanks so much!
very informative, thank you!
Nice explanation. Thanks a lot for this
I swear to god whenever I graduate and start making money I'll donate to your patreon lol.
Thanks for the video! How did you know how much of each (ex: HCl, sodium bicarb, etc.) to add while performing the extractions?
Nice explanation
Professor Dave for the save, as always ❤
Dave and save Rythm
And thanks for another awesome video!
this helped me so much thank you!
very well explained. thanks!
Literally the cutest video ever
Your videos are amazing, thanks so much
awesome explanation 🤙🏽 ty
very helpful. thank you
finally somebody is speaking my languange
Dave you are the best
Looking fresh proff🤘
Thanks a lot . You make the picture more obvious
You are a life saver! Thank you!!
Very nice job! Thanks
Thanks Mr Heisenberg
Thank you for this ❤️
this was crazy helpful lol thank you so much!
i literally love you
At 7:58, how do we get rid of the Na? Does it just remain in the dried solution? Is it filtered?
Thank you so much, that was really helpful!
Very nice for ur all videos sir.😊💛👏
Wow thankyou so much for the explanation!

Oil separates on its own by time just to make sure its pure 👌
Very helpful. thanks!
I came here to learn about Solvent Extraction when it comes to extracting lithium from black mass, a product of battery recycling.
Thank you professor ❤️
u saved another day of mine
prof thank you for your deep explanation. but which is our product in separation of benzoate with HCL?
