Recrystallization and Melting Point Analysis

[@nathanmermilliod3135]

Perfect video and explanation of concepts, and just in time for my students’ lab practical on recrystallization. Thanks Professor Dave!

[@23100Battlefield]

I had my lab on this three weeks ago! Wish Dave had this video earlier, you really have labs late in the term, it's our exam period rn

[@thomaseddyson362]

Thank you. I always appreciate the effort you go to with your videos. Well presented with just enough of the required ephemera.

[@harrybrielmann189]

very complete! And I agree that trituration (forcing the solvent out by the addition of a less soluble solvent) often results in a less pure product.

[@hananehanane3860]

I hope to see more techniques explanation in your channel. Thanks Prof Dave

Hey, I have friends and roommates that work for Thermo Fischer scientific. What a fun coincidence that they sponsored one of my favorite KZbinrs.

[@hennascornerpodcast]

you are saving the life of every ochem college student thank you so much

[@eddielikesfish7114]

i literally just learnt about this in chemistry lol. we are going to be making asprin with this method in january

[@louisnemzer6801]

My favorite organic chemistry purification method!

[@martinarenzi4744]

Thank you Prof Dave! As always so precise and clear

[@MSA_fansite]

I love you mr.dave you are really helping beyond imagination

[@prixynealojado6998]

You're my hero, Professor Dave 🫶

[@nicco-sixty]

Will you do more in-depth concepts in multivariable calculus, like the Jacobian matrix?

[@similosihlegqalisisa8211]

I'm subscribing now Prof❤❤❤

[@StephOnyia]

You are a pro 😮 Including the guy in the laboratory 😊

[@RandomChemistry]

such a high quality video and explanation

[@Dylan-cv7kj]

Science is so cool

[@triple_gem_shining]

Moon is flat tho . Lol jk

[@ariiibaby05]

Right

[@markshort9098]

Yes, yes it is

[@WanderTheNomad]

5:17 Why do we have to use the minimum amount of solvent? Is it just to avoid wasting it or something? Or is there another reason?

[@keypo790]

Its because the experiments relies on Solubility Curve.

[@Ibrohim3-m3t]

its better to use the smallest amount of solvent to minimize the amount of material lost by retintion in the mother liqour

[@yodogyz]

I think doing melting point first would further highlight the importance and use of purification. Instead if being like "here's the right way to do something and here's how to check" it would be "okay we got an impure sample, how do I purify it and how do i verify if it is pure" otherwise great video!

[@qingyunzhao]

Wow, are you mainly involved in crystallization

[@milviodeleon4421]

Wow comments on. Good job 👍

[@rozana4470]

When are the other videos coming cause i start OC lab this week😭

[@missionsuccess6323]

. Synthesis of 2-Amino-4-(substituted-phenyl)-1, 3-thi- azole Derivatives

[@TomasElizabeth]

So super cool

[@gamingwithrksaver4868]

We used to do these for derivative tests... and then match the m.p. to literature value to confirm the compound

[@ansammkh1681]

thank you

[@enzoshii]

Crystals did not form in our experiment. What could have gone wrong?

[@Murcans-worship-felons]

Fascinating

[@RevilHermes]

I remember doing much simpler version with salt.

[@ProfessionalGasLighting]

Sometimes I’m scared by the complexity of it, but then I remember future and 50 did this without any formal education 🤷🏻‍♀️

[@rassimsimou1594]

Good

[@LilianKauwo]

Interesting

[@judeboys6409]

This video reminds me of being a meth head in my 20s. Wouldn’t recommend it 😂. I used to “wash” it in acetone. To clean out impurities .. Have no clue what that was doing scientifically. But it sure made you higher 😅😮. Hey Dave. What would be the science of that lol ? You probably more an idea than I

[@harrybrielmann189]

it's ok if the impurity is insoluble, just filter it out while hot.

[@harrybrielmann189]

oh you covered that, nice.

[@chrisaltaawesome]

thank youuu

[@TheCosmicGuy0111]

Wowza

[@krabre1848]

hi

[@tiptop1681]

Finally i can do this with my meth. Thanks

[@Linda-hn3bh]

👍😌

[@LincolnakaOnion]

I want lego set

[@worldsfinestsimp6421]

TIGHT TIGHT TIGHT

[@-JA-]

🙂👍

[@livingcodex9878]

おはようございます

[@desmond3828]

immunology?!

[@krabre1848]

idk whats happening but cool

[@krabre1848]

omg i remember this in year 7

[@KasaJiso]

First comment, day to of “do more flat earth vids they blew up.” Sorry not first I was too long to write the comment :(

[@Gxlto]

Sorry man I dont think he will. It's kind of dead at this point. I hope he does more creationism debunking

[@DavidP089]

2 million subs and your videos barely reach 10k views 🤔🤔🤔

[@ProfessorDaveExplains]

Learn how educational channels work, sweetie.

[@white_isnt_a_race2338]

Educate me daddy

[@sandunimihirangika5363]

Thank you
