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.

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

[@eddielikesfish7114]

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

[@hananehanane3860]

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

[@henna_nenna]

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

[@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.

[@nicco-sixty]

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

[@Dylan-cv7kj]

Science is so cool

[@triple_gem_shining]

Moon is flat tho .
Lol jk

[@ariiibaby05]

Right

[@markshort9098]

Yes, yes it is

[@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 🫶

[@vspqrv9784]

such a high quality video and explanation

[@StephOnyia]

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

I'm subscribing now Prof❤❤❤

[@rozana4470]

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

[@RevilHermes]

I remember doing much simpler version with salt.

[@TomasElizabeth]

So super cool

[@enzoshii]

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

[@gamingwithrksaver4868]

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

[@milviodeleon4421]

Wow comments on. Good job 👍

[@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.

[@user-qe8gy1zv2i]

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

[@ansammkh1681]

thank you

[@krabre1848]

hi

[@Dont_insult_people]

Fascinating

[@rassimsimou1594]

Good

[@harrybrielmann189]

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

[@harrybrielmann189]

oh you covered that, nice.

[@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

[@chrisaltaawesome]

thank youuu

[@TheCosmicGuy0111]

Wowza

[@tiptop1681]

Finally i can do this with my meth. Thanks

[@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

[@worldsfinestsimp6421]

TIGHT TIGHT TIGHT

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 🤔🤔🤔
