How to Purify by Recrystallization

[MarcusTheReverent]

how do you purify or extract ammonium nitrate from fertilizer?

[darkpigion]

Can the purification be made any more efficient than this? It seems like allot of product is wasted.

[DeanMalenko]

@darkpigion not sure if it's true but I think you could keep the liquid that you took away and crystalize that in order to not waste so much.

[soverato3]

is strontium nitrate radioactive? so yes, how much?

[wdb1111]

Wow, this guy could probably make some kick ass meth.

[JOCHSZCH]

can you talk about the difference between deionized water and distilled water?

[demnlordd666]

I recovered strontium nitrate from road flares, after recrystalizing several times and getting a fairly clean result i tried the dessicator bag with the common dryzair granules from rite-aid, cacl2, and it took a couple weeks to draw the water out, and it only dried a 3mm crust on top of the moist crystals :( I broke the crust up but it formed again. I need to use a container with a larger neck to increase the surface area

[beaochi]

is this how Heisenberg make his pure crystal

[Igotdemburgerz]

@beaochi lol lets cook meth

[QUICKMONEY514]

real shiiit



[MrGmanFreeman]

Cocaine and meth...

[MrCoonskin]

Would further dissolving and recrystalization bring more purity or is there a plateau effect?

[kitty6837]

@MrCoonskin It continually keeps becoming more purified, but you will end up with a much, much lower yield. But you can keep purifying and purifying it, but it will never reach 100% purity.

[TheMINDISUE]

Do you change your voice for legal reasons?

[metalhead0jtk]

I have some Strontium Nitrate from an old road flare (I suspect it contains some sulfur too) and it doesn't seem to dissolve in water at all, blame the sulfur. How can I purify by crystallization with something that is hydrophobic and heat sensitive? Thank you

[MAKER6450]

How many people are watching this to learn how to cook meth?

i dont think anyone wants glow in the darl crystals

[MAKER6450]

looks like meth

[starshock01]

After heating, placing the heated solution in the beaker into a styrofoam or insulating container will yield larger crystals but will take longer to cool.

[mresurm]

@NurdRage In another video, I cannot remember which, somebody was asking about the magnetic stirrer hotplates and why they were so amazingly expensive. I was looking on the net and found a stirrer only for $99, and a hotplate stirrer for $299. Not sure if thats cheap, but its something. Check out united nuclear dot com in case you get asked again. ;)

[diegonikki]

you can purify these chemicals with recrystalization

sodium nitrate

ammonium nitrate

potassium nitrate

mostly you can do it with most nitrates they can be purified by recrystalization

but other chemicals idk

[chunkles4774]

*science

[chunkles4774]

@nurdrage what is it can type of sin

[jarheadwithm16]

Can you purify sodium acetate by recrystallization?

[spotlightman1234]

Dear Dr.n-butyl lithium, may i ask what that nasty looking flask was at 0:58 ? looks gross to say the least, but it did make me laugh when i saw it.

[cjdiverson]

Scratch the bottom of the glass and BOOM! Crystal town!!!

[MrGeltabs]

ummm im lookin to purify sum blow...... does this fucking help me?

[TheChemicalGenius]

I have a question. If you synthesize Mercury (II) Fulminate and you get a powdery sort of yield, can you crystallize it by dissolving it in ethanol,and using the same methods as you demonstrate in the video? I understand that Fulminated Mercury's autoignition point is at 180 degrees Celsius. What should I do? I would really appreciate any sort of reply

[J14e11s87u]

Hi thanks a lot; your videos are helping me to finish my thesis actually I´m recovering metallic manganese from spent batteries but I have some questions How long does it take to recistalize MnSO4 ? and How much do I have to boil the solucion up (in percentage)? I´ll be waiting your answer.

[MrPrivatetv1]

is phosphorus toxic to humans ?

[dA55assin117]

Just asking, why does the recrystalization process make the chemicals more pure than the original state?

[Bombermanos]

Will this method work with technical grade KNO3? Thank You.

[dukilaki]

i have 100% pure water

[Legostunt542]

but if i want to purify kno3 cant i just use boiling water and put kno3 in there ,then stir until dissolves and then put it in the freezer

I like your videos.You are my favorite chemist

[xdaftpunkxloverx]

I could never be a chemist. Evidently it takes SOOOOOOOOOO much patience. x_x

[CannaPlant]

This is the first explanation of the process of recrystallization that makes 100% sense and answers all my questions. Thank you!

[steadfast1984]

you can also use R/O water as long as the membranes and filters are high end.

[AngelPLM]

Quick question. I know how the absorbed impurities that are trapped in the crystal lattice of the solid released during recrystallization. But where do these impurities ultimately end up?

[JZThunderhead]

Are you a woman, because you have feminite hands, i am being sincere here, Just asking (sorry for spelling errors)

[SodomGomorrahWaDC]

This guy is totally a drug addict "your product".. And the meth at 0:55 and crack pipe and crack at 1:00...

[ilackedtheheart]

It's organic lab all over again lol. Purification is pretty cool, but such a pain in the ass to set up, and run. Too much water, or add not hot enough solute and you get poor yield. Arg that always pissed me off.

[kuro96inlaila]

nice video nurdrage,can you make a video about fractional crytallisation on how to separate two or more soluble compounds?

[raphackerable]

interesting and informative video

[artea1oo1]

is it possible to use the recrystallization method on pottasium nitrate and sulfur?

[freakin1random]

besides, you can always keep the unpure stuff for other examples.

[Chemateur]

How do you prevent supersaturation? When I try purifying solutions by recrystallization, they seem to end up supersaturating and won't come out of solution until I introduce a seed, and it's not as pure when the crystals grow in a matter of seconds. Maybe these are different, I haven't actually made aluminum or strontium nitrate yet, but in general when recrystallizing, how do you keep them from supersaturating?

[fedaikn]

there is still liquid coating the crystals, even after the second purifying step. i think that one will not get rid of impurities unless one gets rid of the liquid phase. could you get rid of that by washing the crystals in a filter with some ethanol or isopropanol?

[NurdRage]

@fedaikn

the crystals are pure enough for the synthesis of phosphorescent powder.

And you do get rid of most of the liquid, and thus of the impurities, when you decant off the liquid.

[garranechan]

none of u answered so i tried it with sodium acetate myself..

it worked yayz ^.^

[killman369547]

can you recystalize using the method in the iodine video or is that for iodine alone?

[garranechan]

nvm the first question...the trihyrate seems to sperate when it meets oxygen...explination pls?

[garranechan]

in 1 of your vids of the glow in the gark things u need sodium acitate..in another1 u make sodium acitate trihydrate(exuse my spelling).

1)will that work for that vid?

2)will this purifacation work for the impuritys in the sodium acitate trihydrate?

3)im just beggining chem. houners in 8th grade and looking up cool things to do and understand the chemistry ,

thanks

[levikfc]

can u make any chemicals that are cheap and easy to make that dont make a really bad smell?

[NurdRage]

@levikfc

sorry, nope

[AZMALING]

@NurdRage what are you making next?

[radioactvchem]

That'd be great if you make a vid to purify mno2 one question do you know where I could get sulfuric acid cheaply? Thanks

[radioactvchem]

would you be able to purify the MnO2 from the battery like this?

[NurdRage]

MnO2 isn't soluble in water so it requires a chemical purification process.

if i make ask, what do people use MnO2 for other than an h2o2 catalyst? if the use is interesting i might do a video on it.

[radioactvchem]

@NurdRage i was thinking of making the potassium permaganate from your other video and wanted to see if i could purify the mno2 to get a better product. As for other uses im not really sure. I am just a beginning chemist :)

[NurdRage]

interesting, i am putting together a video on how to refine manganese dioxide. It requires nitric acid or sulfuric acid though.

[tomwmloppe]

My science education in chemistry was a disaster.

I fared well, learning about everything around me, but in chemistry, I don't get it.

I am a new utuber, computer student, and recently I joined the 21st Century

by getting a 'smart phone'.

[misko112100]

why does inpure aluminum nitrate look wet?

[NurdRage]

@misko112100

hmmm.. good question, never really found out.

If you should, let me know :)

[skybattle2]

Can we purify ammoniumnitrat?

[coolliger]

Which method should be used to purify sodium nitrate?

[TheCLockMen]

Or NaCl, SORRY!

[TheCLockMen]

I know I posted a ton of comments, but I,m learning.

Can recrystallization work for lots of chemicals, such as sucrose on NaCl?

[Dvnn1408]

Is that your real voice? lol

[thehellsyeah123]

ok so i have a really big problem with the nurdrage channel

how come you guys have 15 thousand subscribers!there should be WAY more these are some of the most interesting videos ive seen on youtube!!!!

[NurdRage]

Good question, i think people just aren't interested in what we do. Science just isn't as popular as twilight and harry potter.

If you can figure out a way to reach more people then let me know :)

[ENGterrorman]

@NurdRage

a way is showing chemicals that can be used in pyrotechnics e.g kno3 experiment got a lot of views.

how to make potassium perchlorate or chlorate would be good

[NurdRage]

i was already planning a few more combustion videos (including kno3) but i've seen channels taken down because they showed that sort of thing. i guess we'll just have to see.

[ENGterrorman]

can this be done with potassium nitrate ? like using the SR(NO3) method or boiling?

[blink182chase13]

So being tottaly serious, cai i use this to puify lye? cause i got the drano crap and i heard its not bery concerntrated. Please answer..any one.

[np0405]

@np0405 rather than putting it in a dessicator bag****

[panzuman]

since this is a purification vid i figure this is the most relevent how would i purify garden dust for the sulfur its about 25% sulfur P.S. im trying to make a shell from nighthawkinlights videos

[CluelessPedestrian]

You are my favorite Canadian Web Savvy Youtube Chemist! Though I think you're the only Canadian Web Savvy Youtube Chemist...good luck on your future endeavours!

[CuteNpurrfic]

HI Thx for the help. Instead of repeating the process i washed my crystals with pure acetone. Will this affect my crystals o.o/ I dont think so though.

[stonerj0e]

can THC be recrystallized ? i know it might be a dumb question but seriously i have heard of oils and solids being formed but what about crystals ?

[mrblisterfist]

no.

[stonerj0e]

ill definitley not take the answer from you ! anyone else ?

[mrblisterfist]

according to Erowid : "No... THC is actually an oil, and you can not get it to crystallize at room temperature. If you attempt to boil off the liquid, you will just destroy the THC and end up with ashes."

"Anyone else ?" Who in the fuck do you think you are ? My intelligence quotient is in the 98th

percentile !

[eggbertsmith]

Ah...modesty.

[panzuman]

would you llike a peanut?

[girrrrrrr2]

yes.

[Grundalizer]

You'd end up most likely losing more THC than you would gain. It'd be better for you to just smoke it as is, or grind it up and rub it over a really fine mesh screen you can buy at art and craft stores for making homemade paper. You get all the THC crystals

[ohmichael203]

I didn't catch the filter rating.  A coffee filter is about 10-20 micron is this enough?

[jungleman68]

finally done with ochem

[blkmirror]

re: recrystallizing Sr(NO3)2

Was that dissolve in smallest amount of HOT water? Or cold water

[Guitar0wner]

now how do u make a nuke?

[kickit246]

LOL, I think that may be partly physics as well. Could be wrong though, I haven't made a nuke for a little while now. :P

[mejawmeyaw]

stupid man

[frietjericcardo]

could i use cooked water instead of tap/ distilled water?

5/5

[Mike480537]

boiling out impurities = distillation

[odysseus9672]

I think you have that backward. In distillation the desired chemical is what evaporates for condensation elsewhere, whilst the contaminants remain behind. It sounds like what you're describing would be heating something so that some contaminant boils before the desired chemical, which would be different (though I don't know a name for it.)

At least that's how I understand it.

[donnelrj01]

@odysseus9672

That's fractional distillation.

[Grundalizer]

What is cooked water?

[MSTLOM]

Cooked Water is what a Father makes when a child is being born!

[EinYamakasi]

You know, with all this amazing info alone the Nurd already has a strong following (almost cult-like). With the DVD, (I'll totally buy it regardless the price) that status will totally go past cult.

[antiswattt2]

wut? a dvd! youre gonna be famous ^^

[blinking801]

You know ever since I saw that old black and white movie "Madam Curie" I wondered how this process works. In the movie the Curie's performed several thousand recrystallizations as a final step in the separation of Radium from Uranium ore. Thanks! I also wondered how they knew when to stop.

[weldmaster80]

and useing MY tap watter will probably actualy make it less pure LOL, I have a PPM meter, and my tap watter is about 500 ppm total desolved solids.... now I dont know what allll those solids are, but I can tell you they taste disgusting

[soyunclonyque]

Please, post a video indicating when's the DVD due for release :)

[hirodagger]

man i would love to do this but i cant get any of the chemicals that are needed =/

[TruJezter]

As always you videos are great. I just wanted to thank you for taking the time to make these videos. I also look forward to a DVD. Long Live NurdRage!

[TzerMaan]

Can I download all of your videos on youtube and make it into DVD for educational purpose ?

[NurdRage]

@tzermaan

I'm actually trying to put together such a DVD myself. Once i have a few more videos, as well fix some mistakes and edit a few issues, i'll release such a DVD directly.

[TzerMaan]

Thank you, I shall buy it once it is released.

[AkatsukiDesign]

Having recently discovered and subscribed to your channel I am very impressed. Love it. And the voice is cool!

[NurdRage]

@AkatsukiDesign

Thanks

[myrdale]

Don't discard your mother liquor, you should be able to save 3 or 4 worth and then go though your recrystallization process again to collect that material you would have lost.

[NurdRage]

@myrdale

I tried that but the purity just wasn't good enough to make phosphorescent powder.

[Kryptic890]

Thanks for another video! Can't wait for more

[Kryptic890]

Oh, one thing. Do the Dysprosium and Europium nitrates also need to be amazingly pure?

[NurdRage]

@Kryptic890

if you started with %99.9 pure metals, used distilled water, and distilled nitric acid, then no, they'll already be pure enough.

[hyperbob101]

hehe i am following along with everything you do. right now i have lioke 5 glow sticks i made using your steps that i haven't even broken

[drahyden]

Recristalization, great technique. Thanks for positing this vids, you are really making a excellent service of inciting the love for chemistry on people.

[tashi37]

nice cool vid

[zapo147]

JUST did a lab using this technique...

[murtaza13]

SICK!

[ryan50ryan]

64% reduction. is there a way to extract any of the chemical from the left over water?

[NurdRage]

@ryan50ryan

simply let it dry. But it will be chock full of impurities, and useless for making glow powder. If you have other uses that can tolerate the impurities then go for it, otherwise its best just to discard it.

[Valendros]

With a name like N. Butyl Lithium, it's no wonder you became a scientist.... har har har. (it's a knee-slapper)

[sciencoking]

[billytalentrocks345]

Will this method work for sodiumacetate trihydrate? Well, I maybe have to get rid of the trihydrate thing, making in nonhydrate (correct spelled?), but how do I do that?

[Th1s1sMyAcc0untNam3]

strontium nitrate... hmmm, in our language that kinda sound wrong

[cyrixproductions]

Same here :D

[vashthestampid]

Why cant it be filtered? before recrystallization?

[messitup]

really cool method , and video, is there other ways to purify substances?

[NurdRage]

@messitup

Lots, and Lots, and LOTS.

So many that i can't cover them all,

i'll cover ones as i need them.

[Matthew99600]

WHO LIKES ROCK CANDY!!!

[personperson666]

hey if you do the recystalation over and over (i saw that they we geting bigger) does it evenaly make 1 big cystal?

[NurdRage]

@personperson666

While it does improve the crystal growth somewhat, eventually you reach a limit where the size is dictated by other variables like size of the container, temperature, humidity, etc.etc.etc.

[personperson666]

dude you should try to make i giant cystal geting the perfect temp right sized container etc etc etc then sell it on ebay youd make at least 3$ besides that are you like a chemist or something or like a smartness of people

[NurdRage]

@personperson666

several days of work for $3?

I get paid more than that working ten minutes at my job. (Research scientist)

[cobrasniper555]

That would be something I'd like to do after the Army. I'm 18, and plan on going through college afterwards. I'm good with math and chemistry (organic as well). Any suggestions for classes or majors to take special interest in?

Thanks

[personperson666]

dude i was jokeing but i was could you

[mafl25]

Wow you loose so much product in that process, is there any way of getting it back? I want to see that next video!

[NurdRage]

@mafl25

yeah, but it's now chock full of impurities. After all, to make one portion purer the impurities have to go somewhere.

Just save the discarded liquids and dry them. If you can find a use for them that isn't sensitive to impurities then go for it.

[renatadevin]

Is there anything that glows AND explodes?

Is there any reason why distilled water is better than deionized water?

[milotickz]

Of all the scientists on youtube, you NurdRage, are the BEST!!!

[mykeljee]

great, informative

[Roflshamans]

I doubt that's his real voice. It doesn't sound natural, he likely decreased the pitch. Somewhat like "Fred" (the popular youtuber) , except Fred increases the pitch.

[deathadder32]

I'm so excited for the next vid

Oh, and nice sweater by the way xD

[haze656]

show to make make crystals

[GnosticDjinn]

make is a command line execution for compiling a program. You can't just make make crystals. Also, the other videos where they made the chemicals in impure form are located on the channel.

[HitMeUpOnMyCellPhone]

i doubt his voice really sounds like that... i remember hearing a tweaked voice that is almost exactly the same.. tone u could say, as this.

[Reverendwyotech]

I heard he has five testicles, that's why his voice is so deep.

I also heard he's the Stig, from Top Gear. Either way he's Awesome!

[PuppetMaster303]

intelectuals are awsome i dont know why but nerds always have really deep voices like me

[nebonit]

The man that does these video's tweaks his voice I believe (If he does I dont know why)

[Marty2azn]

I think he does it so nobody knows what he sounds like.

[MapleFr3ak]

That's his actual voice.

Cannot wait for the next vid!

[kwibjo123456789]

YEAH NEW VIDEO!

[Pipewing]

You make some great videos. I do wonder why you didn't heat the strontium nitrate just to speed evaporation. Where do you find solubility vs. temperature information? or is it something you just remember from doing so much?

[NurdRage]

@Pipewing

Generally, the slower the recrystallization is done, the purer it is.

Sometimes you can come across the solubility tables in the literature, other times you just have to try it yourself. :)
