Reaction of copper with nitric acid

[@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?

[@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.

[@SyntheticFuture]

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

[@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

[@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 =)

[@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!!!

[@DriftKingNL]

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

[@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.

[@tonnerebolt2993]

This video is helping people after 9 years in chem test

[@winstonpauwels4058]

What a beautiful experiment, wow love it!

[@Kazuo1G]

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

[@FirstResponderAlex]

Our teacher demonstrated this to us on our third day of school and it was awesome!

[@elainecheatham1678]

Lovely concise demonstration. Thank You

[@Kostja08a]

Mana potion!

[@Arastelion]

Magic for days!

[@GokantheHusky]

XD

[@Katharina_VT]

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

[@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

[@SciMedUK]

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

[@kastro6789]

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

[@hamzakhairi4765]

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

[@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 :)

[@jasonsweet228]

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

[@pedrour2009]

Excellent and inspirational video. I will recommend it to my collegues.

[@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−

[@KarinaWang]

what concentration does the acid need to be at

[@elevenjonesav]

I'm doing this lab in a couple days. Now I can't wait.

[@Morkvonork]

You should use low concentrated nitric acid in the second flask because the nitrous gas can disolve in it. It will absorb much more than plain water.

[@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.

[@miraclegodfrey2193]

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

[@Siamzero1994]

As he said, it's there to hinder the hazardous gas from leaking out

[@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

[@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?

[@jacobcox4276]

Just beautiful!

[@madinkan]

best chemestry question ever!

[@oscarnotyourbuissines6027]

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

[@brunoaraujo2700]

that is such a beautiful colour at 2:10 wow

[@0begoo0man0]

What is the chemical decomposition of the blue color?

[@juanvelasquezsantos3449]

What is the tube called that is transporting the water from one flask to another? How and what is causing the water being absorbed by the tube that goes from one flask to another?

[@declan.fleming]

Collectively we just call these delivery tubes. The water is drawn back in in a process of "suck back" - the air in the main flask gets quite hot during the reaction and expands. As the reaction subsides, heat is lost to the surroundings and the gas begins to contract, drawing the water back up the tube as the pressure drops. This would only happen a little but for the water then dissolving the NO2 gas in the flask .. as gas particles dissolve in the water, the pressure drops still further and draws even more water in, dissolving more gas .. etc etc.

[@giovannifigueroa2430]

where does the h2o come as one of the products?

[@thegreatga]

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

[@lovishmonga1378]

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

[@haiderchem1665]

very nice experiment

[@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?

[@marypearlcacayuran2245]

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

[@deseanmccloud2107]

What’s that brown gas?

[@MallenCraft]

That's a really awesome blue!

[@liemmatheuszik3311]

What Reaction Type is this?

[@Nogorn]

how long will the blue glow last?

[@MrHelvegtable]

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

[@JohnDoe-rx3vn]

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

[@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.

[@xrayPL]

as mr bean would say: MAGIC!

[@hobomnky]

can someone explain what exactly the glass wool is doing?

[@jihncrazy]

What sorcery is that?

[@missdapperduck1389]

Wow, that was amazing.

[@luoyuwuyu]

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

[@mistertheguy3073]

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

[@arkomisra7563]

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

[@jorgen485]

How to make a mana potion

[@surajpatel2877]

Go to Walmart and get this bottle called a placebo.

[@joshuahaines795]

[@cheesewizard8943]

Except then you get a deadly poison effect

[@phyllislawhorn7205]

now how do you get te copper back out?

[@itscndyfrrr]

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

[@Francinun]

In the reaction, isn't it supposed to be NO as a product instead of NO2?

[@Francinun]

Thank you!

[@zahirfarzay2129]

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

[@elainew.5301]

What type of chemical reaction is this?

HOW TO TITRATION OF RED COPPER OXIDE ANY IDEA

[@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%?

is this a redox reaction

[@ROCKaholic]

Cool stuff. Now show us something with fluoroantimonic acid!!!!

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.

[@nvoewvobwurgfbondoqb]

Why would copper react with hno3 and not hcl?

[@chemistrywaalla]

Get Like Me.. Probably bcoz nitric acid is very good oxidising agent whereas hcl is not... It is not acid displacement reaction but redox reaction majorly :))
