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.

I'm a visual learner, and these videos are SOOOOOOO helpful! Now I'm not as nervous about messing up in lab!

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"

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

This is really helping me out with the lab report I forgot I had, thank you!

This deserves a lot more attention and likes, it was beyond thorough !!!! Loved it !

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

Professor Dave another great video, direct and to the point. Keep up the great work. Cheers!

Another absolute banger by Professor Dave. My 10 page pre-lab outline couldn't explain it worse. Bless

You are amazing explaining each and every detail! I will definitely recommend you.

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

Yet another excellent video to help with my orgo lab. Thanks prof Dave!

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.

Did an extraction for the first time last week - wish I had the video before then. It's perfect!

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

super helpful rn that im doing an organic chemistry lab online during this pandemic. Thanks for the upload!

What a bloody legend, absolute gold.

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.

Such a good lecturer. Thanks for helping me increase my MCAT score

So happy to discover this channel. Thanks!

That was awesome! Thank you! please publish more of these videos!

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.

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!

Literally you make my learning to become easier ,,,,,I appreciate you alot

thank you so much! extraction finally began to make some actual sense 👏

Thank you so much! Really helped me to improve my understanding.

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!

This video is super helpful! Thank you so much!!

you are the greatest person ever for explaining chemistry❤️❤️❤️❤️

Thank you so much professor for making this video 😇😄

Top notch content. Congratulations.!

WOW! your video is saving me on this report i procrastinated. You are truly the michael jordan of organic chemistry.

Actually nice video.... That method was difficult to me,but after watching this video i could understand...thanks for you..

And thanks for another awesome video!

Thank you for such a great explanation!

these videos are so helpful, I'm doing my degree at uni and still use these for my chem practicals if I can

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!!

Tank u for this videos. You are amazing. Industrial chemistry student from Saudi Arbia❤❤

very informative, thank you!

very well explained. thanks!

Thank you so much, that was really helpful!

THANK YOU SO MUCH PROFESSOR DAVE

this helped me so much thank you!

Nice explanation

Wow thankyou so much for the explanation!

prof. dave strikes again!

Thanks for the video! How did you know how much of each (ex: HCl, sodium bicarb, etc.) to add while performing the extractions?

this was crazy helpful lol thank you so much!

You are a life saver! Thank you!!

Oooh! I love your new hairstyle, professor :D And nice video, as always!

awesome explanation 🤙🏽 ty

Thank you professor ❤️

Very nice job! Thanks

prof thank you for your deep explanation. but which is our product in separation of benzoate with HCL?

That's so cool and clear. Thank you so much from Russia.

This video. This is everything.

Very helpful. thanks!

OMG thanks so much this video was incredibly helpful it pretty much cleared what was happening in the lab. WOW

Question: Which is more effective in separating the components of an ink? Water or alcohol?

I am here learning as an aromatherapy student lol, thanks so much!

fascinating, thank you!

i literally love you

great video!

Dude!!!! You are so smort that my teacher uses your videos for lessons

Thank you!

I'm so pissed. My professor made this sound way more complicated. Thanks Dave.

DUDE IM SO THANKFULLLL

Literally the cutest video ever

At 7:58, how do we get rid of the Na? Does it just remain in the dried solution? Is it filtered?

Thank you!!

Single-handedly destroyed my chem teacher in explaining this. Thank you!

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 😅

Thank you.

I did this in my lab but I was wondering what the purpose is of cooling the aniline salt before adding the NaOH?

u saved another day of mine

Please sir make a video on Separation and identification of the binary organic mixture ( e.g. urea and salicylic acid)

In 3:14 won’t the choloroanaline and benzoic acid react since they are both acid and base?

wouldn't the carboxy-group in benzoic acid also interact with the water molecules when aniline is washed out of the solution? thank you for your videos!

u r really great thank u very much

THANK YOU!😍😍😍😍😍

always check the density! solvent like DCM will be at the bottom.

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.
