Make Copper Sulfate from Copper and Sulfuric acid (3 ways)

[nindocomic]

@NurdRage Amm... could you do the chemic ecuation of the reaction? Cuz I want to know it please?

[SmexyBeastChannel]

These videos better not be available to users in the Middle East... 

[Dewkeeper]

@SmexyBeastChannel

Yes, because those nasty savages must not be allowed the secrets of us civilized westerners who are ever moral and vigilant against the injustices of the dirty easterners; they simply cannot handle such progressive things such as science and knowledge! It would just blow their heathen minds... /sarcasm

[SmexyBeastChannel]

@Dewkeeper Spot on my friend. Spot on.

[rosabellis]

How long did it take for the huge crystals of copper sulfate to grow?

[ARKESAN]

NICE THANKS!!!!

[inotrad]

Why is hydrogen peroxide needed? Is sulfuric acid with copper okay?

[w0xy]

is this walter white's recipe?

[spooky1000]

are those crystals easy to break or are the tough?

[Zarnirox]

It's beautiful...

[samsaras]

Looks almost like sapphire!

[mousaey]

can you electrolyse a solution of MgSO4 with copper anode?

[SolarisBlitz]

It's always the colorless chemicals that create the most exciting colors.

[liveoles]

Well then we don't need conc sulfuric acid for the last method you showed right?

[BenW1991NE]

so how did he get the crystals? just let it sit?

[zombierobopirate]

does it taste good it looks delicious

[astriknon]

I've done this with sulfuric acid and #2 copper pipe using the electrochemical process. A new side note I learned is if you were to dip steel into the copper sulfate solution it will be lightly plated with copper. I did this to a hammer over a year ago and it is still shiny copper to this day.

[freitasnetuno]

@NurdRage can we use higher voltages? Like 5kV?

[prithwin]

Is this what they call azurite?

[ZFQFMB]

@prithwin Azurite is a basic copper carbonate which doesn't dissolve in water and is a deeper blue. CuSO4 is copper sulfate which is the same as the rare mineral Chalcanthite.

[ZFQFMB]

I'm currently making CuSO4 via copper, sulfuric acid and air. It takes longer than actively oxidizing the copper, (In a large flat contain with plenty of surface area a few days.) but I find that it uses up all the acid and I don't need any additional chemicals or equipment. Best of all it also works when making copper acetate from clear vinegar.

[MasterGamer86]

@NurdRage It looks delicious

[ombra30]

i'd like to it at home but i dont know how to find sulfuric acid

[LightProductionsTV]

Im only 13 and im guessing now isn't Sulfuric Acid H2SO4?

[MrSuednym]

What concentration of Sulfuric acid do you need for the Electochemical method of generation? And, does it need to be performed in a hood/outside?

[MrSuednym]

What uses are there for Copper Sulfate? Other than looking at. I'm only a first year chem student forgive my lack of knowledge.

[kevinkever2000]

is this your real voice

[oreo792]

all this damn science!

[willardb123]

How many times did he manage to say "copper sulfate" in that video?

[Airwalk486]

Have you ever thought about joining Aperture science?

- sincerely, GLaDoS

[TheCrazyFinn]

@Airwalk486 He did, but he quit after he discovered the cake is a lie.

[inverseactuality]

@Airwalk486

I can see it now

"In this video we will be making a deadly neurotoxin..."

[MrBoombam1]

Can copper acetate be used for this?

[elflordbob1]

or buy weed killer

[AfroSamuraiTheMaster]

i bet this guy acted out the dialogue for Jigsaw

[MrNickisking]

How did you get rid of the majority of the sulfuric acid before you boiled the blue solution?

[P3arlJang]

My new favorite shade of BLUE!!! :)

[Envyiwur]

I selld them for 100k money

[commetsmasher]

I remember back in eighth grade one of my friends bet me 20$ that I wouldn't lick a copper sulfate crystal... Probably the nastiest thing I've ever tasted.

[soverato3]

im used to make copper sulfate like you but than i took a copper pipe in the knee....

[demnlordd666]

i am trying the 3rd way right now and have a nice sky blue solution at the bottom of my reaction vessle so I guess I am winning. I am using an old atx powersupply that was moded to power it. if you buy the solid core 12 or 16 gauge house wire from the hardware store you can get a section and only strip part of it for the posative electrode that goes to the bottom, then ya don't need to buy a little scrap of tubing or any thing.

[mts133]

I went to home depot and got this stuff called ZEP root kit in the plumbing section. It is pure copper sulfate for 12.00 for 2 pounds!

[mzh3000]

I got this kit to grow crystals.

You boil water and pour in the powder. It will grow emeralds or rubies.

I am guessing they are fake but the fact you can grow rocks is still cool.

[Desmaad]

It's interesting how solid copper sulfate seems to glow.

[MegaScienceguru]

i hope nurdrage will see this comment and do a video about it im subcribed and waiting

[MegaScienceguru]

i live in canada so its fairily imposible to get chemicals like these but i noticed that epson salts are made of magnisuim sulfate srry for the spelling errors but could i not do a single replacement reaction with some copper pipe?

[Sophesumer]

Copper Sulfate crystals are so purdy

[RhayvenBlood]

Kinda looks like Rock candy o:

[icycolds]

unuptanium!

[mcwario13]

if i replace the sulfuric with acetic acid could i make copper accetate?

[michael36693]

nice voice

[patrickdonovan7]

always good videos to get mah chemistry fix

[ThePinkamina]

ooooooooooooooooooooo.... preettyyyyyyy

[kaiyaofong]

i bet he knows how to cook meth

[ScienceTry]

@kaiyaofong Even if NurdRage does know how to cook meth, it doesn't mean he's cooking it. And secondly, just because he encourages home chemistry doesn't mean he encourages cooking meth. Geez, don't bring drugs into the picture as the war on drugs has already significantly affected home scientists in lieu of availablity of supplies.

[DennisNguyen88]

:O when i was a kid, i bought this little "grow your own crystals" kit, and i made this in a little plastic box!

[lyrison]

My copper sulfate solution has been left to evaporate for more than a month, and it doesn't look any different from when I put it in the container. Did I do something wrong?

[GTHaroFITBMX]

16 people cant make copper sulfate cuz they are gay these videos RULE!

[12414666]

Cant i mix MgSO4 and Copper accetate to do this?

[DaffyDaffyDaffy33322]

...i made a house out of dirt

[Almontmarine]

can i heat it to dryness?

[kittypie070]

My favourite shade of blue...and such beautiful crystals...!

[ervthesaint]

3:47 it transfroms that fast!

[fatlizzard19]

im in 9th grade, all of my classmates only use vocabulary used in the jersey shore. i am compleatly souronded by half, no, not even quarter wits. it is realy nice to listen to people who are smart. this girl asked me if you could swim up a tornado. and yes, she was a prep whos mind never leaves her cell phone.

[tommy9688]

Another way to avoid copper ions to oxidize at the positive terminal is to use a tin electrode instead of copper.

[NurdRage]

@tommy9688 that would defeat the purpose, in this video we WANT the copper to be oxidized and go into solution to form copper sulfate. Preventing that would prevent us from obtaining the desired product.

[claireb321]

what is the concentration of H2SO4 used for the electrolysis method?

[SmexxyWarr]

or as it called HHO gas

[3287490]

where do you get all your chemicals?

[Tutorializer100]

is not the copper sulfate posionus?

[Aviatorsmith]

@Tutorializer100 It is not.

[DisillusionedAmerica]

Step number (5) should be: React (NH4)2SO4 w/CuO. I'm not even sure if any of this would work; that is, the precipitation of soap, by raising the pH of the Na2SO4 solution with NH4OH, and using the ethanol as a solvent and phase transfer medium for the (solid at room temp) stearic acid. If this method did work, it would use cheap raw materials, and the soap formed could be recycled by converting it back to stearic acid with a cheap, OTC acid like vinegar. Just an idea I've had kicking around.

[DisillusionedAmerica]

Instead of wasting H2SO4 to make CuSO4, how about: (1) synthesize Na2SO4 from plaster of paris and washing soda; (2) dissolve formed Na2SO4 in NH4OH solution, w/ 2x molar equivalent of NH4; (3) add stoichiometric amount, in relation to Na, of stearic acid, after first dissolving in enough ethanol to keep fatty acid liquid; (4) Remove "soap," which should form, & float on top of the aqueous layer, replacing fatty acid; (5) React (NH4)2SO4 solution w/ Cu; (6) Heat tetraammine CuSO4; drive off NH4.

[NurdRage]

@DisillusionedAmerica 6 step synthesis with plenty of wastes Versus 1 or 2 step synthesis with few or no wastes.

all those extra chemicals would probably add up costing a lot more than H2SO4.

If you want to do it just for the didactic value then go for it, but there are more interesting complicated synthetic processes out there, like making luminol for instance.

[DisillusionedAmerica]

@NurdRage Thanks, and I didn't intend to step on any toes, btw, if that's how I came across. I really appreciate your videos; they have helped me and countless others learn. You're probably right about my proposed procedure costing way more than just simply buying H2SO4 and Cu, IF it even worked. The sheer volume of NH4OH needed alone would likely end up being a royal pain in the ass to deal with, lol. Not to mention the CuO would have to be made, which would be energy intensive. Thanks again.

[esteban7628]

@NurdRage what the hell did you just say???

[lyrison]

@DisillusionedAmerica You can get 96% concentration, high purity sulfuric acid in 1 gallon bottles for $24 at Ace Hardware. I just bought some yesterday. It is a plastic bottle in a plastic bag titled Rooto Professional Drain Opener. Great stuff.

[DisillusionedAmerica]

@lyrison Thanks. Actually, that price sounds like a pretty good deal, IMO. I have an ACE nearby, maybe I'll check if they stock a smaller, more manageable-sized bottle of H2SO4 drain unclogger, like in 16 oz or something. I don't need much of it; my interests involve mostly small electrolytic cells.

My whole interest in synthesizing it was mainly for the academic challenge, plus it would be fun to find a reliable way to make H2SO4 out of gypsum or epsom salts as a sulfate source.

[lyrison]

@DisillusionedAmerica Yeah. I bought the H2SO4 for chemical synthesis. I already made copper sulfate and manganese heptoxide. You ever heard of manganese heptoxide?

[antiswattt2]

@DisillusionedAmerica that sounds quite more advanced (: but my experience was that the copper DID react with 37% H2SO4, but really slowly.. heat and electricity will speed up the reaction, but electricity will speed it up most, you dont have to use highly concentrated H2SO4, you can just use the weak 37% 1 mole from car batteries (; but TACS, when heating that, does that remove the NH4 then?? making it anhydrous CuSO4?? i saw it reacted alot better with Mg that way (:

[IodineVapour]

@DisillusionedAmerica Tetramine Compounds are explosive so heating would decomspose the Tetramine (explosivly)

[clarrotXmen]

it's so pretttyyyyyyyy lol

[MrAcid1000]

Maybe CuCO3 with H2SO4

[tartdbusdrvr]

i did this experiment for a 5th grade science fair and i won haha .. i remember those days .. i loved science

[UserName9587]

CAN I USE A PENNY

[tartdbusdrvr]

@UserName9587 well pennys are no longer made of complete copper , just a thin coat .. so that probably isnt the best idea

[ThePhDChemist]

I have better explaination for your video, i mean for reactions at anode and cathode! It could be also explained like this, I mean it is same: You are producing hydrogen peroxide which reacts with copper to make copper oxide, which reacts with sulfuric acid to form copper sulfate!... Hmmm, if you used carbon electrodes in h2so4 solution you could make hydrogen peroxide which i am now making. I AM SO HAPPY!!! :) :) Soon I will make video HOW TO MAKE HYDROGEN PEROXIDE ;) Subscribe!

[NurdRage]

@ThePhDChemist please research "overpotential" and "reduction potential" in the context of electrochemistry.

[joeydealbuquerq]

The hydrated copper sulfate crystal plates makes the grown crystal look like huge masses of crystal when they are in fact sheet crystals lol :( not so funny when you get those.

[alauta1996]

I think I made copper sulfate... I use Ammonium persulfate in etching circuit boards and I store the used liquid in a plastic bottle. The bottle have been outside few months and I found some crystals from bottom of the bottle... The crystals were the same color as powdered copper sulphate an dissolved to water and the liquid is blue. Now I am waiting to it vaporize.

[PSPortalMaker]

Could you make copper acetate in an upcoming video? It's a very easy reaction with household chemicals (Acetic acid and H2O2, in 5% and 3% percentages respectively). Thanks.

[Khaied345]

Is there any way to get sulfuric acid from Aluminium Sulfate and water, or aluminium sulfate and other stuff?

[pravinpatel1982]

i am mfg. copper sulphate

[TeknoXIII]

@happylinkfan231

I think you just add the Copper Sulfate to boiling water and stir it until it dissolves. But you keep adding the Copper Sulfate until you can't dissolve anymore, this is called a "saturation" I think. But anyways just let the liquid evaporate from the saturation and you should have crystals. Remember don't touch or disturb the crystallisation process or it won't work

[happylinkfan231]

i have copper sulfate but its in a powdery sand form i dont have any sulfuric acid but can i still make the crystals with water or some other household chemical?

im an amature and i really like how the crystals look

[Almontmarine]

i dunno if my country allows sale of copper sulfate, and we don't really have sulfuric acid in here except the school labs and universities who have licenses. trying hard to get copper sulfate though.

[TeknoXIII]

@NurdRage

Is it possible to store this in a liquid inside a container, e.g oil? Or do you have to store it in an air tight container

[HLiNaKRbCsFrUun]

@000JERRY0000

@superriku11

Yes you can, but only canadian pennies will work (as far as I know), and only those made prior to 1996. Now, they are made out of plated steel. The shinier the penny the better, as there will inevitably be some oil contamination from people's hands, and from the wax coating from production. Also note that american pennies do not work, because they have a tin core. Remember that one penny weighs about 2.35 grams.

[TheWarbirdPhoenix]

Oooooooooo pretty...With Science!

[VRABACBL]

So the process is following: H2SO4 +Cu=CuSO4+H2, right? My reall question is: When all sulfuric accid turns into copper sulfate, and oxidation of copper beggins(Cu2O), where is the oxigen comming from?

[BDawg1942]

@VRABACBL oxidation has nothing to do with oxygen. it means the loss of electrons in a substance.

[Almontmarine]

@BDawg1942 agree, and that guy's equation is also wrong. u need half-equations for each of the 2 terminals. +ve and -ve terminals.

[stanleyyv]

Are copper sulfate crystals safe to store in a glass container as decoration?

[NurdRage]

@stanleyyv As long as the container is air tight. Yes! :)

[ggglllllll]

@NurdRage Is it safe to wear as a neacklace?

[uaintwright]

can't you just buy some old stock foot powder from the early war surplus thats the same i think?

[NurdRage]

@uaintwright Its always easier to buy stuff. I like making stuff sometimes to demonstrate the science. Also the principles learned can be applied to other experiments where you can't buy the chemicals.

[zip1ziltch2zero3]

you should do a video that explains how to use electrolysis to separate hydrogen from oxygen, without oxidizing any chemicals. i heard that platinum works well. is that true???

[MrPracticeRoom]

It's so strange to see a reaction of copper being bright blue XD

[win7dot]

Thanx.



[Hortonfan123]

At 0:56, does tap water work? Or does it have to be, um, pure?

[megamolenaar]

can u send me some coppersulfate by mail??

[pyrioni]

why add hydrogen peroxide?

[94nailson]

@pyrioni Para oxidar o Cu e este produto reagir com o ácido, pois o Cu (metálico) não desloca o H+ do ácido. O ácido reage com o óxido formado na oxidação do metal.

[goman9078]

i wanna make copper sulfate ok. no wait first i have to make acid, ok no wait first i have to make 39 other goddamn things

[firen777]

blue tiberium

[Iceincorperated]

is there an alternative acid that can be used for this experiment?

[ohmahgawdfilms]

do want "3g of aluminum powder to 8g of iron oxide"

[dmn513c]

@ohmahgawdfilms thats to make thermite.. not this lol

[ohmahgawdfilms]

@dmn513c oh I know. I just wanted him to make it :D

[nickroselund]

how do you make red green and blue crystals? i know how to make the blue and piezo.

[singar997]

i m 13 yrs old and i wanna make 1 of this but i don't understand a thing he said in the vid and have no equipment to make it.

[Caboose129]

@singar997 then dont try this the chemicals at work and the processes of making these crystals is dangerous for people without expierience

[singar997]

@Caboose129 ty for the warning and did i even say i will try to make 1 and didn't i say idk wth he say on the vid so i won't even bother try to make 1 and u just make science goes boring again.

[Metalist76200]

That is such a beautiful crystal.

[lordanjan1]

What is the reaction for the second one?

[niron200]

I don't really get how you can go from that powder to the big ass crystals.. Help?

[TheChronicler90]

@niron200

Unless you turn that powder back into a liquid, you really can't. The amount of evaporation, among some other factors, alters the size of the crystals. As explained in the video, if you let it evaporate naturally, it'll make those nice, large crystals. I could be wrong, though, so ask other people as well.

[lordanjan1]

I tried to use the 3rd method (before I saw this video) and it failed miserably. Now I feel dumb because I have easy access to both H202 and HNO3. And is boiling the solution the only way of obtaining copper sulphate because I am not a fan of vapourizing toxic chemicals?

[TheChronicler90]

Are the crystals safe to put up on display?

[mewrox99]

@TheChronicler90

They are poisonous if swallowed and can irritate skin. So just keep them in a vile and it should be fine, I wouldn't keep them out in the open 

[TheChronicler90]

@mewrox99

I'm okay with that, thanks. :) I've got two more questions, would inserting a rock I get out of the front yard for the crystals to grow on alter the chemistry in any way, and how do I make sure the crystals get as big as the one's in this video?

[GiantJboy400]

if you filter the mixture what's the name of the substance left in the filter paper? thx

[TheTomiTomo]

can i use carbon electrodes ??

[TheMrCwany]

Po co ci kwas azotowy, przecież można była zamiast niego dodać azotanu(V) amonu lub potasu. Wszystkie saletry mają właściwości utleniające tak jak kwas azotowy.

[jenno1997]

i done the 1 way in school

[ishola96]

what would be the chemical reaction of the 1st method ??

[StrokeMahEgo]

Instead of letting it evaporate out ( to get the crystals) would it also work to use the dessicator?

[mattcysiewski111]

can i use Sulfamic acid (H3NSO3) as a substitute for sulfuric acid

if yes what is the byproduct of the reaction thank you!

[abzdefg321123]

I love chemistry lol..

[jeffddow]

for the battery u dont need sulfuric acid

[thegod2k2]

Ok I figured my last ptoblem out, However I now have a new one I can't get the copper sulphate to precipitate out? any Ideas?

[thegod2k2]

What is the crud that drops off at 2:15 onwards, and how do I remove this from then end product?

[420darklotus]

Just go buy root killer and save all this time.

[rockerbabe400]

lmaoo!!! fellow nerds :)...i nt a nerd tho; stupid h/w :(

[unisailor]

Very nice, many thanks!

[kdavethomas]

Would adding epsom salt(MgSO4) or glauber's salt to the electrolyte increase the yield?

[MegaChemboy]

@kdavethomas probably not, and it would contaminate your final product

[kdavethomas]

Would adding epsom salt(MgSO4) or glauber's salt to the electrolyte increase the yield?

[raudonas21]

why does he boil the water so that it evaporates?

[TheGhostrider1100]

I it possible to make different colored crystals?

[HunterRooneySweeney]

Use hot white distilled vinegar and regular hydrogen peroxide. When you throw in copper you get copper sulphate

[coolliger]

@HunterRooneySweeney

no you dont, you get copper acetate

[AnimeGirl10129]

Sooo pretty! This is why I like science... :D

[ochanster]

can i use 100 mL of 3 % hydrogen peroxide?

[Limpingfury]

Is it possible, if you leave the remaining mixture to evaporate, to add a previously made copper sulfate crystal to have it "grow"?

[firebomb37]

cool

[EKOSMUNiDAD]

.

...OOO... O ...OOO...

.

[dhsjango]

I want..... to lick it.

[AgentCROCODILE]

I have been etching PCBs for a while and noticed the ammonium persulphate turning blue. Is this CuSO4? (it dries out to blue crystals) - just checking. :)

[superriku11]

Can you use pennies to make this? :D

[hawk151515]

@superriku11 Pennies have zinc metal in them An its agunst federal law unless its for teaching a class

[BlurConfusion]

@hawk151515 no you can destroy coins as long as u dont try to spend the messed up coin

[hawk151515]

@BlurConfusion Where the fuck do you live I was ripped a new one by a cop for sticking a penny on the train tracks when i was ten

[BlurConfusion]

@hawk151515 you can destroy them but putting them on a traintrack is dangerous

have you ever seen one of those souvenir penny squashing machines?

[hawk151515]

@BlurConfusion Yea my mom has a couple of them An the cop seemed more pissed about the coin then me being near a track

[Lowman9]

@superriku11 yes you can but you have to remove at first the Iron in the pennie. its a little bit difficulter with a pennie like with these way

[TheGamerReturns]

@superriku11 No because modern pennies are only about 2.5% copper metal but pennies from the 1940s are about 40% copper.

[kitty6837]

@superriku11 Pennies these days contain very little copper. If you get pennies from sometime before the early 80's, that might work.

[animusterror]

@superriku11

Pennies today are mostly made out of Zinc,

The last time they used pure copper was in the early 1800s
