We show 3 ways to make nitric acid based on two different chemical approaches both of which can be done using easily accessible materials. Warning: The procedures in this video produce large quantities of toxic gases and deal with highly corrosive acids. All work must be performed in a fume hood with proper safety equipment. And all apparatus must be glass to withstand the acids. Chemically, nitric acid is made by bubbling nitrogen dioxide into water. So the objective in this approach is to generate nitrogen dioxide. This can be done by reacting hydrochloric acid, a nitrate salt and copper. Around 80grams of sodium nitrate, over 30 grams of copper and 100mL of hydrochloric acid (37% 12M) are the quantities needed. The exact amount isn't critical. For usable concentrations, the amount of water being converted should be small, around 20-50mL. Any source of nitrate is usable including potassium nitrate, ammonium nitrate and even nitrate-based fertilizers. You can use our previous video on testing for nitrates if you want to determine if yours can be used. http://www.youtube.com/watch?v=f5M3rUqaEYs The tricky part now is leading the gas into water. Two approaches are shown in the video. In the first approach three containers, such as jars are place inside each other to force the gas to go into the water. This is very inefficient but is very simple to do. The better approach is to lead the gas out of the generator through a tube and into a chilled container of water. The water that's converted into nitric acid can be replaced with hydrogen peroxide for better yield. The chemical waste that's generated contains the valuable copper used before and recovering it is worthwhile due to todays high copper prices. This is simply done by putting in enough aluminum metal that it reacts with all the acids and copper in solution to create a slurry of copper. This can be filtered to obtain a residue of copper. Its highly contaminated but can still be used to make more nitric acid. For further information on the chemistry type "copper and nitric acid" into google. The hydrochloric acid and nitrate salt behave as nitric acid (with nitrate from the salt and protons from the hydrochloric acid) and dissolve the copper releasing nitrogen dioxide gas. You can use other concentrations of hydrochloric acid but you need to decrease the amount of water added to keep the concentrations the same. Finally, the last way of making pure nitric acid is to react concentrated sulfuric acid and a pure nitrate salt (NOT fertilizer) and heat it in a glass distillation apparatus to distill over the pure nitric acid. Stoichiometric quantities of both reagents are recommended for maximum yield. We get our glassware from chemglass or VWR
Instead of actually understanding the origin of the rule or why it applies you rely on unscientific catch phrases and insults? Your so called "basic rule" only applies to certain limited set of circumstances. Primarily it applies to adding water to concentrated sulfuric acid. But if you don't believe me try this: Grab some vinegar in your kitchen (an acid) and add water to it. NOTHING will happen other than getting some diluted vinegar. Try to be smarter and less insulting will you?
You forgot to add that vinegar is most commonly 5% acetic acid
@Jason Enns dont sniff glacial acetic though! woo! burns your nose hairs!
I learned in High School chemistry 40 years ago to "Add acid to watah, just like you oughta."
I haven't run into any circumstances where that caused problems, even with vinegar, so it seems like a useful guideline.
"Only nitric Acid can dissolve copper " ?
@Brandon Knight im glad i wasnt the only one who heard this, but to dissolve copper means that the acid and coppers by product is water soluble. So hydrochloric acid can destroy copper its byproduct isnt water soluble. I believe is the answer
"If you blow air into it, it fumes!" "Do not inhale."
My all-time favourite nurd rage quote :)
That's not even what fuming nitric acid ACTUALLY is
pKai3 I know right? He sounds genuinely excited when he says it, then becomes serious again
Nitric acid smoke... don’t breathe this!
Blow, don't suck.
haha
Need this so i can make the revival formula
WAIT, SEND THE SMOKE SIGNAL!! IM NOT THE ONLY ONE AFTER ALL!!!
next stop, explosives. powerful explosives.
@Heads Mess They had people collecting and fermenting chicken shit and hog piss from hundreds of farms, year in year out and then purifying the smelly stuff. That's serious lot of work, not all that pleasant . I guess I don't want it bad enough for that :)
@Ruben Proost You don't need a license for stump remover.
@Ruben Proost stump remover......potassium nitrate
I’m going to make gun cotton
NITROGLYCERIN hehehe
I wanted to show a wider range of approaches. If i didn't use water some viewers may get the impression water can't be used. Then i'd get questions like "couldn't you use water instead of hydrogen peroxide?" by showing both we see more perspectives and get a better handle on the underlying chemistry and how it can work in different ways.
Now all I need is some glycerin and sulfuric acid...
what's the greek word for power?
@Charniel Duterte The Greek words for "power" are δύναμη <> dýnami (power; streght, force, might and potency), ξουσία <> exousía (power; authority, dominion, control and sway) and ισχύς <>
ischýs (power; forece, streght, might, mightiness).
umm thanks? i was referring to the dynamite
Hehe explosives
Haven’t tried to purchase sulfuric acid but about 25 years ago I remember my grandfather buying concentrated sulfuric acid from the plumbing supply in Brooklyn. No I.D needed. Wonder if thats still a good place to get it. Also glycerin can be purchased at any pharmacy over the counter or even at some supermarkets in the aspirin isle
Who’s here after watching the first episode of Dr. Stone ? :)
Me bruh I was checking to see who else googled it
What is dr. Stone
Uhhh me
Me
Sounds dangerous, do you have sufficient safety measures in place?
Yay more views!
Thanks for your quick reply!
The King of Random Grant?!
Thank you, Grant.
Love ya, grant<3
rip grant :(
I can't believe that he didn't reply to your comments
4:05 I wanted to just point out that you can distill fuming (above concentrated) nitric acid, you just need to use concentrated nitric acid and concentrated sulfuric acid and distill. The sulfuric acid likes water much more and will keep it in the flask while the almost pure nitric acid distills over. Great video!
how did i get here...oh yes i started with why is gold so valuable and clicked like a zombie and now i'm here.
Go for it :)
yup, go for it!
Dr.Stone??
Yeah me too
this is freaking cool!!!!
Hey! I would like to know the equation for that reaction.
Thanks for this, I can start making revival fluid now
When you watch too much Dr.Stone and you wanna do the magic stuff.
I have 2 pounds of aluminum nitrate, can I use that?
@ubuntupokemoninc Yes, you can use any nitrate salt.
6:00 looks like a bong
Took about an hour so we will skip that part x3 love it
On the last reaction you need to do the laugh. Very cool! Thanks.
"Do not inhale" 🤣
Yay, I can't wait to use this knowledge in my day-to-day life!
I mean, who's bothered to make a cake?! This is way better!
Great video! Thanks for making this! When using sulfuric acid, can you use battery acid from an auto shop, or is that too dilute? Do you need to boil it down to a higher concentration?
You have to distil it
i like when it spilled at the end. its quite funny :D
Brilliant as always! .. Been viewing all your video's ... I knew very little about chemicals and science but I'm learning a lot from your videos here, ... I'm waiting for you to produce a video of chrome plating, similar to the glass mirror but this time making the chrome on the outside of the glass and also being used on plastics and metals. I have been trying to work this out myself and I'm nearly there, obviously most of the same chemicals from Tollens ... Anyway, love your videos and keep them coming and thanks for sharing ;-)
Thank you. That is exactly the information I was looking for 3 weeks ago when I asked for help with quantities of the reactants. Unfortunately, it is 3 weeks too late. Thanks anyways.
I love your videos so much! I'm in Gen Chem 2 in college and these make me appreciate lab that much more!
not everyone has an inert glovebox n their attic, lmaooo
I marvel at the knowledge persons like your good self possess, thank you for sharing.
Man, I love making Aqua Reginaaaaaaaa
Wow, I can remember making up a nitric-sulfuric 70/30 bright dip for our brass/copper parts before nickel plating...
Hello Friend, I would like to ask Do you know where I can find and buy ceramic CPUs at a good price?
Of all the videos you've uploaded, this is one that I wish you'd revisit the most. It's really dated and it shows, but it's still a great video.
Very interesting. Thanks for the videos. :-) It's good to have skill sets and knowledge how to use it.
What is reaction occuring in approaches 1 & 2 producing NO2?
como fazer ácido fluoroantimonico sbhf6???
Here thanks to Dr Stone .
Great demonstration video. Though I understand that yields will vary, I would have liked to see what the final volume of the final products measured to give me a general frame of reference to calculate a material cost analysis.
I'm debating buying nitric acid and paying the huge hazard fees vs making it myself. The general need is to find something to dissolve copper.
Where do I dump all dead reactioms amd leftover chemicals?
amazing dude thnx so much!
Can I use distilled to concentrate urine for this reaction, or will the other impurities make other byproducts
you could, although you might need to dilute the acid a bit before trying it. I must make the suggestion through that if you have sulfuric acid and a nitrate salt you can go to the third method which is more efficient and produces much higher quality acid and produces less wastes.
Dr. N. Butyl Lithium :DD When you dont have friends so you give nickname yourself
I can almost hear the "oh s***" as the 98% nitric acid spills onto the bench! :O
I have wanted to know how to make this for so long. Thanks for the video.
"Do not inhale." For some reason I started laughing.
