I hope I caught you to tell you 2 important things 1st if your acid is concentrate enough you must store it In brown glass because nitric acid tends to be decomposed from UV radiation(thats why your distillation apparatus got full of red fumes (nitrogen dioxide) because the sun decompose your product) and 2 you may be careful because sealed fuming nitric acid botle tends to builds up pressure and maybe it explodes on your face when you trying to open or even touch it !

Another good video. Like Mike Hanley mentioned, I'd suggest measuring the density to figure out the acid content. I'm not sure exactly how concentrated you're needing it but if you do have a bit of sulfuric acid and need it stronger you can always mix it in and distill from the mixed acid for a quick upgrade. I can see a yellow glow in your acid but did it look greenish in person to you? I've done this method with sodium bisulfate and sodium nitrate and when I ran just the salts together the acid I was collecting was greenish. Teflon tape for sealing the joints was an interesting idea I might try if I do it again. I was using sulfuric acid as a joint grease.

I'll definitely be measuring the concentration at some point, and thanks for the idea for drying it! I'll be sure to do that if I ever need RFNA specifically. At this stage, I don't have any use for concentrated (or even azeotropic) nitric acid, but I'll keep it around just in case. The colour of the nitric acid is an interesting property of the nitric acid/nitrogen dioxide mixture. Under most circumstances and concentrations, the acid appears yellow due to a small quantity of dissolved NO2. However, under the right conditions, the equilibrium which holds NO2 in solution will shift towards making N2O4, which also stays dissolved in the acid to give a green colour instead. I'm not sure exactly which conditions favour the formation of N2O4 instead of NO2 (it's likely to be temperature I suppose), but it's nothing to worry about since the chemistry of NO2 and N2O4 are extremely similar.

Fantastic!

Adding a little bit of water is a good idea if you don't mind a slightly lower concentration. It's still important to use an excess of bisulfate for the reaction though.

It's the costs of shipping it that make the price go high, though most sellers combine all the costs and say that shipping is "free", which is absurd and makes the price seem very high. The requirements for legally shipping nitric acid are insane and cost a lot to implement. If you ever order any and there isn't a large amount of packaging, containment and safety steps implemented in the packaging, then the seller is pocketing that money and putting others at risk by shipping it in a hazardous manner, which is illegal as well. If you ever order nitric acid, always order from a reputable company with great reviews. Otherwise the simple act of just ordering it could put people at risk unnecessarily. It's generally easy to tell who these companies are as they have somewhat crappy and suspect listings online. It's not hard to find what I mean. But yeah, it's the costs of shipping that make it high, not the acid itself. Just wanted to clarify that for those who don't have experience in chemical distribution and sales. 🙂

Could you make the sodium bisulphate anhydrous before going this? If you answer this could you also help me understand the ratios. 1.5 molar equivalence, I don't know how to calculate. Would 3 parts NaHSO₄ to 2 parts KNO3 by weight be close enough to what you mean?

@ScrapScience

2 жыл бұрын

You could make the sodium bisulfate anhydrous if you wanted, but the main mechanism by which the reaction occurs requires the reactants to melt. The melting point of the hydrated form of sodium bisulfate is around 50 C (which makes it very easy to use in this reaction with modest temperatures), but the anhydrous form melts at above 300 C. While it would work to some degree, running a reaction at over 300 C is generally very difficult, and likely would decompose the nitric acid considerably. The ratio of NaHSO4:KNO3 I refer to in the video is not based on mass, but is instead based on the stoichiometry of the reaction. It's not possible to explain the fundamentals of this in a single youtube comment, so you'll need to do some research here. As a starting point, you'll need to look up topics such as the 'mole' and the 'molar mass'. Once you've understood these ideas, maybe search for 'stoichiometry basics'. There are plenty of textbooks online which can explain the ideas much better than I can. As a final note, if you are planning on doing this yourself (I mean, I don't know if you actually are, so this paragraph might not be relevant). I don't want to be rude here, but based on the fact that 'molar equivalence' is an unfamiliar term, please don't try this without extensive research. I'm not sure about your experience with chemistry, hazardous materials, or PPE, but this really isn't the project to do without an extensive understanding of the fundamental chemistry of the reaction and the substances involved.
