Reaction of copper with nitric acid

Declan Fleming shows how copper can in fact react with some acids by demonstrating the reaction of copper and nitric acid, producing a visually stunning reaction. Read the article that accompanies this video in the November 2011 issue of Education in Chemistry at rsc.li/EiC611ec
This is part of the Education in Chemistry Exhibition Chemistry series: chemistry demonstrations to capture your students' imaginations: rsc.li/EiCExChem

[@phubans]

Man, chemistry has fascinated me from a very early age, when I found my uncle's old flasks, beakers, and test tubes. It's too bad I never actually got into it though, because damn, this stuff is awesome.

[@DriftKingNL]

So this is how they make Nuka Cola Quantum. No wonder so many wastelanders die.

[@dalbysc]

The blue green at the start is not copper nitrate-- it is a nitrato complex. The copper 2 ion is blue and is formed when the water is pulled into the reaction vessel.You can find the equation on this video and a literature citation which explains details of the reaction. kzbin.info/www/bejne/fpWxqqikfdqhqtk

[@declan.fleming]

very cool! .. thanks for sharing :)

[@dalbysc]

Declan Fleming You are welcome. Send me an email and I will send you a pdf of the article we did on the reaction. [e-mail]

[@TheJvlustosa]

Whats the formula for the complex?

[@dalbysc]

Did I send you PDF of the publication concerning this demo? Here is a portion from the article. On the basis of the spectra of the solution and the reported equilibrium constants, the equation for formation of the green solution is [Cu(H2O)6]2+ (aq) + NO2- (aq) = [Cu(H2O)5( NO2)]+ (aq)+ H2O(l)

[@declan.fleming]

you sent it to me thanks - I asked about getting the correction added as a note over the top of the video. I will bring it up again :)

[@KarinaWang]

what concentration does the acid need to be at

[@StealthAssasin1]

Nice color

[@mrlokalist]

Wanto drink the blue stuff...looks tasty

[@Kostja08a]

Mana potion!

[@Arastelion]

Magic for days!

[@GokantheHusky]

XD

[@Lost_Souls_Gaming]

YAY! Now I can restore my mana. :D (\ô/)

[@stephenstone149]

Yes, you can dilute it with deionized water, and if you add NaOH (sodium hydroxide) a drop at a time, a blue precipitate will form, Cu(OH)2. Copper hydroxide. You can test the liquid after several drops at a time with litmus paper to know when it's turned basic. Add more water and heat, stirring until it boils, and the Cu(OH)2 will turn into CuO, copper(ii) oxide. Filter this, and use H2SO4 (sulfuric acid) to drain it into a beaker, then add zinc, which will dissolve and leave you with pure Cu.

[@HariKrishnan-he6fc]

Brother presence of Ca,Fe,Al in about 0.1g / L will it affect Cu(OH)2 precipitation?

[@milliefreddie1]

That blue is so nice

[@GokantheHusky]

That blue is called azure blue.

[@joshuahaines795]

Shodan Computer Search Engine It's more of a sky blue. Azure is slightly darker. At least if you're talking about the end product. And that's just my opinion. Anyhow, that blue is pretty. And blue.

[@Themuffinman488]

+ben stedall And that car isn't

[@Kazuo1G]

Now THIS is what every middle and high-school student dreams of doing! :D (I know I did!)

[@dex1lsp]

That's an incredible color.

[@jordanelliot2419]

Pro tip : watch series at InstaFlixxer. Been using them for watching lots of of movies recently.

[@lancecarl8649]

@Jordan Elliot Definitely, I have been watching on InstaFlixxer for since december myself =)

[@SyntheticFuture]

Love this demonstration, first saw it at my highschool. The reaction is quite violent but really cool to watch.

[@miraclegodfrey2193]

Why can't the product be Cu(OH) +NO2

How to make a mana potion

[@surajpatel2877]

Go to Walmart and get this bottle called a placebo.

[@joshuahaines795]

jorgen485 if you don't mind drinking copper then sure

[@cheesewizard8943]

Except then you get a deadly poison effect

[@thegreatga]

at 3 points in this reaction I was expecting a explosion and pain

[@Squish120]

Wow that's a lot of NO2, you can prevent the formation of NO2 by using hydrogen peroxide in with the nitric acid, to oxidise the NO2 back to HNO3 as its formed. This way you get more efficiency from the acid, able to react with a larger amount of material.

[@kastro6789]

I did that whole process as a laboratory experiment in my chemistry class :D

[@oscarnotyourbuissines6027]

The only question now is: Will this restore my magica?

[@xrayPL]

as mr bean would say: MAGIC!

[@igormitrov8710]

***** what about Mercury+Dry Ice+Lava(or Hot Water +200degrees) ? can u make it :)?

[@GokantheHusky]

How to make a mana potion. Do exactly the same thing this video just showed.

[@tonnerebolt2993]

This video is helping people after 9 years in chem test

[@weiming1998]

Nope. The Cu2+ ion, if ingested, will induce vomiting, so poisoning from ingestion is very rare. You would get a rather sick stomach though. Not exactly the best way to boost mana.

[@SciMedUK]

Great video, well-done team, thanks for sharing!

[@goatontheroad7692]

remember guys, aside from copper nitric acid acts upong your fingers as well as your trousers!

[@madhursehgal8764]

What about Mercury with antimony oxide.. Red Mercury?

[@paolipable]

coppercab liked this because, Copper = orange = ginger. wich is why his name is "copper"cab. and now, LETS DO SOME TROLLING

[@UnnamedEnder]

no it wasnt, and wasnt you =/ i just say that someone liked too much and accidentaly cliked the dislike bar :D

[@arkomisra7563]

I am not getting how is it happening because copper is below hydrogen in reactivity series

[@chemshort5225]

I need your help badly. I am preparing NO2 gas in lab from this reaction by adding 1g of Cu to 2ml of HNO3. But how do i quantify them, how do i present in an article because pressure cannot be calculated iwhile its preparation

[@dalbysc]

The green material produced at first in the reaction is not copper nitrate. Copper nitrate or rather the [Cu(H2O)6]2+ ion is blue. The green color is due to a copper II nitrato complex. Exact structure of these complexes are not known,but equation below is a likely possibility. Equations Cu + 4 H3O+ + 4 NO3− → [Cu(H2O)4(NO3)2] + 2 H2O + 2 NO2 [Cu(H2O)4(NO3)2] + 2 H2O → [Cu(H2O) 6]2+ + 2 NO3−

[@Null-o7j]

But shouldn't it be more likely to form copper nitrate since the reaction consumes nitric acid from the solution, rather than h2o?

[@rameshchaursiya2102]

aap serial number se chemical daru aur batao kaun pada hai pahle kuchh dusra number mein kaun chemical teesra number mein kaun chemical jalal kar taiyar Kiya jata hai

[@ThatOneOddGuy]

I did this with copper coins and i got some orange paste as a product what us that stuff

[@MLorao1]

Mana potions are blue. Health potions are red. RPG 101. :)

[@GothicSprinkalMuffin]

and this is how you make a mana potion. any questions?

[@elainecheatham1678]

Lovely concise demonstration. Thank You

[@quinndoust5264]

MAN NOW I GOt CHEMISztry ON THE BRIAN

[@Fryiffy]

YES i figured out how to make mana potions!

[@laupstad]

Really? They should make warning labels on stuff like this!

[@udaysavaliya9869]

HOW TO TITRATION OF RED COPPER OXIDE ANY IDEA

[@sunflowersare-yellow]

i had to research an interesting chemical reaction and write about it for my chemistry homework and found this, THIS IS SO COOL!!!!! WHAT THE HELL I LOVE CHEMISTRY!!!

[@merrimac10]

cool NOW CLARIFY WHAT THE HECK U JUST DID IN MATH TERMS??

[@ladyirkin]

you can simply drain it down a sink with tons of water.

[@nickbhalo]

does there have to be a minecraft joke on every video?

[@liemmatheuszik3311]

What Reaction Type is this?

[@wavydavy0389]

This man made a glass of nuka cola

[@jacobcox4276]

Just beautiful!

[@dalbysc]

The green material produced in the first flask is not copper nitrate. Copper nitrate or rather the [Cu(H2O)6]2+ ion is blue. The green color is due to a copper II nitrato complex. Exact structure of these complexes are not known,but equation below is a likely possibility. Equations Cu + 4 H3O+ + 4 NO3− → [Cu(H2O)4(NO3)2] + 2 H2O + 2 NO2 [Cu(H2O)4(NO3)2] + 2 H2O → [Cu(H2O) 6]2+ + 2 NO3−

[@GoldenGunAPB]

@nikola96uf he mentions at 1:22 that the water is pulled up after the reaction cools down. when the gas cools, the pressure in the reaction flask is lowered enough to create a sort of vacuum effect

[@DD-nv2vg]

I want to drink that potion.........

[@lykenth08]

I have some gold with bits of copper that i dont want. Can i use nitric acid to get rid of the copper with out removing the gold?

[@cowpacino]

I don't think so, remember there is still the Cu(NO3)2 in solution. You might be able to precipitate it out and treat the remaining solution like you suggested, but I would ask your local government or waste disposal service for more specific advice.

[@zahirfarzay2129]

Why there’s reaction between copper and nitric acid, not hydrochloric acid?

[@mathiasxx94]

Can i lead this gas into the reciever flask of a distillation of concentrated sulphuric acid and a nitrate salt to create very concentrated nitric acid, near 100%?

[@hamzakhairi4765]

In our ASAP Chem Class the Nitric Acid was concentrated to 15.8 Molar just a ballpark range

[@Madurjafro]

Is this how Nuka Cola Quantum is made?

[@owen889]

Can this be performed at a desk without a fume cupboard ???

[@MrHelvegtable]

Because the flask cools down and the gas lowers in volume and sucks in the water which cools down the flask even faster

[@junimperial8143]

Try to dissolve aqua regia a copper and alluminum.it is true i can make a new nictric acid? Messgae me please thanks

[@cfsharp23]

You could breathe in the red-ish gas coming off of the acid and it would turn back into nitric acid in your lungs :D

[@marypearlcacayuran2245]

I need help. How to get the solubility of copper in nitric acid thanks

[@giausjulius4]

So this is what Jean-Luc and that one chick drank after they killed Shinzon? I bet Data would have liked it.

[@andrewnorton8486]

Follow up question. Once the NO2 dissolves into solution near the end, what would we have for a final product. Not pure Copper nitrate solution correct?

[@jasonsweet228]

Thanks! I'm brand new to this, so catching on pretty good :D

[@jowonbin]

Yes sir....oh who am i kidding. I'm talking life lessons from a person who does cigarette reviews on youtube.

[@adriani9432]

The forbidden energy drink

[@Pixelbox3]

is this is en exception to the rule that acid with metal forms salt and hydrogen but wheres the hydrogen

[@mistertheguy3073]

so what is in the flask at the end? I presume nitric acid, water and copper nitrate?

[@weiming1998]

Or just add excess zinc directly to the leftover green solution to obtain pure copper metal...

[@missdapperduck1389]

Wow, that was amazing.

[@MrSohGoh]

I preformed this experiment in lab last week

[@Spudwellington]

that gas looks toxic as all hell.

[@luoyuwuyu]

If I saw this in high school I wouldn’t have to become a phd in chemistry to have my own humehood

[@brianradon4780]

Mana potion.

[@TheHuntermj]

Not if you have a health potion!

[@lovishmonga1378]

Why does cuno3 does not show it's colour without water

[@girjabaghel7899]

Nice sir

[@JohnDoe-rx3vn]

The water is also used to recover the nitric acid, right?

[@TheMajoung]

No no its the summoning potion

[@0begoo0man0]

What is the chemical decomposition of the blue color?

[@Ilovelazers]

But a fermented spider eye and gunpowder in it to make a splash potion of slowness

[@sandeepsharma-bi7zv]

Any way to recover copper from this?

[@leewilliam3417]

Thankyou 😊

[@automan1223]

How romulan ale is made.....

[@RandomDuude]

So real life scientists actually DO work surrounded in colorful bubbling bottles! O_O

[@chahevartanian2066]

Yes! I'm in my senior year chemistry major and we did this reaction in an inorganic chemistry I experiment for a qualitative determination of copper. This was so beautiful as everyone was taking pictures while the other was working under the fume hood. The gas produced is NO2 which is a toxic gas.

[@destroyerdragon2002]

@@chahevartanian2066 at my job we call it NOX gas... it is toxic and can potentially detonate.

[@itscndyfrrr]

how to know the solubility of the copper in nitric acid?

[@experiment0003]

what witchcraft is this?!
