Making Sodium Nitrite (An Ingredient In Making Nitrous)

- When sodium nitrate and charcoal are intensely heated, an oxygen is bumped off the sodium nitrate converting it to sodium nitrite. Sodium nitrite is a completely different chemical, and will be used in the near future in the production of nitrous (N2O), also known as laughing gas.

Epic video and very helpful too since nitrites are also annoyingly hard to get where I am so being able to make them so simply is great :)
Thank you! I can appreciate the difficulty in getting nitrites. It's what pushed me to get this reaction done.
They banned nitrite, and made mental health meds harder to get. Lawmakers have no clue what they're doing.
You just saved me so much time and effort, lol. Thank you. I'm about to try and use a kiln, though, 🤔. I mean, a reaction box, lol. It's got a burnout plug on top, so the smoke will dissipate.
12/10 vid.
Interesting idea. I have found over time that doing smaller amounts at a time seems to work better. Rather than a large amount at once. Good luck!
Its illegal to buy pure here in the uk. For obvious reasons. However, as mentioned in vid, you can buy preserving salts with it 8n, but its 0.6 percent

Mixing everything in a homogenous powder may seem like a good idea but it would most likely end up in a runaway , high temperature reaction with a beautiful zero yield at the end.
The charcoal (powder) is theoretically added bit by bit to molten NaNO3. It will ignite by itself (around 350^C) partly due to high temperature of molten NaNO3 and the oxygen released by decomposition to NaNO2 + O (decomposition starts above 350^C)
I don't think he's got much of NaNO2 anyway, most of the stuff is just a mix of unreacted NaNO3 and Na2CO3 .
Molten NaNO3 reacts rapidly with the CO2 generated by the oxidation of Carbon and forms carbonate .
NaNO3 reaction with HCl doesn't give the brown NO2 gas , while NaNO2 reacts strongly with HCl and the brown gas evolution is unmistakable. Fizzing when reacting the resulted crystals are an indication of carbonates , especially if tested with acetic acid.
Not a very good way of making nitrite, at least not Sodium Nitrite .
I’ve found that the starch method and the lead method both give much higher yields than the carbon method. It sucks that nitrites are so hard to get now because some idiots promoting them as a self deletion method (sounds awful btw). Bubbling NO2 through a sodium carbonate solution by dissolving copper in HNO3 works well too.
Fancy seeing you here. I tried every. Single. Possible method I had ever read about and personally found starch, lead sponge, and calcium formate (in that order) to be the most effective reducing agents for good yield and purity. Calcium formate was easily the best because it oxidized to calcium carbonate, which was super easy to separate completely.
I'll have to try that!@@integral_chemistry
I Made Some Nitrite And The Method Was Much Easier, React HCl And NaNO3 And Copper To Make Nitrogen Oxide/Dioxide Gas And Bubble It Through Sodium Hydroxide Solution (I Tested The Final Product And It Has Very High Nitrite Amount) But Please,PLEASE Next Time When you make Something THAT Toxic Add A Warning At the begining Of Your Vid, Thank You
Mixing and crushing everything into a homogeneous powder likely increases yield a lot, instead of burning carbon crumbs in a KNO3/KNO2 soup ;-)
try get potassium from bananas lol and next drop on the water
Could you do a titration to see how much NaNO3 contamination you have ?
The amount of NaNO3 is negligible, if there's any at all. When NaNO2 is formed the liquid hardens immediately even though the temperatures are very high. By rinsing off any NaNO3 in the pan (and I overdid the rinsing on purpose), the NaNO2 left behind is very, very close to pure.
@@cranialconstruction2218 but NaNO2 is much more soluble then NaNO3 so it would be carried away as well and just during the reaction, the carbon can react with NaNO2 as well to form carbonates, I've done this reaction myself multiple times, and each time it's contaminated
I'm not sure what you're asking. Sodium nitrite doesn't combine with carbon very well if at all. Once it's heated to around 650 degrees F sodium nitrite breaks down to sodium oxide (which then is burned up), nitric oxide (ends up in the air), and nitrogen dioxide (ends up in the air). You don't get any carbonates.
I also sampled the sodium nitrite making multiple slides to look under a microscope. I did this to see if I could find any sodium nitrate crystals, as their much larger and look very different from the sodium nitrite crystals, as you could see in the video. I didn't find a single sodium nitrate crystal.
Could you please direct me to a video of yours doing this reaction? I would like to see how you did it.
you do get carbonate formation albeit the reaction is messy like you said (nitrite carbonate oxide etc) but it shouldn't be in any amount that matters too much
Ok. What carbonates form? Please be specific.
I wonder if it’s any mix fuel with this oxidiser that you make can be flash powder? 😅😅🎉
It's possible to make flash powder using sodium nitrate
Would premixing finely ground carbon and nitrate alter the outcome and improve or reduce yield?
That's an interesting question. If you abide by the general rule that finer materials will react faster, it could shorten the time it takes to convert all of the sodium nitrate to sodium nitrite.
@@cranialconstruction2218 I actually saw a better way of making sodium nitrate: melt some sodium hydroxide together with the sodium nitrate and then carefully and slowly add bits of sulfur.
3 NaNO3 + 2 NaOH + S = 3 NaNO2 + Na2SO4 + H2O
After that you can separate the sodium nitrite from the sodium sulfate by dissolving it in ethanol or methanol.
@@cranialconstruction2218 I tried it. Nitrate:carbon 80:20 finely ground together in stainless steel pot with lid on gas stove. Ignited after about 1 minute, filled house with smoke. Dissolved all in water, filtered, reduced, crystallised and dried. 91% yield. Thankyou, this is an excellent method. I previously wasted nearly a litre of HNO3 bubbling NO/NO2 through NaOH with very limited results.
How do you test your yeald?

Btw can u make a video on How to make Sodium Chlorate using graphite electrodes pls?
Crush carbon and nitrate while dry into a mixed powder, then heat, yields will improve.
