It might be, but I don’t have any that would react too violently. If I have an acid leak, I’d rather have bases nearby to neutralize it. The most important things not to store together is flammables and oxidizers.
thanks. How about sulfuric acid + calcium nitrate ? bing AI says that : When sulfuric acid (H₂SO₄) reacts with calcium nitrate (Ca(NO₃)₂), it produces calcium sulfate (CaSO₄) and nitric acid (HNO₃). Calcium sulfate is typically in solid form, while nitric acid is in an aqueous solution. Do you think that AI is right?
That should work, but the insoluble calcium sulfate is a huge pain to deal with. I’ve heard of people having it destroy glassware. I would recommend reacting the calcium nitrate with sodium carbonate to form sodium nitrate and calcium carbonate, which can be filtered off, and the sodium nitrate crystallized.
@@RiehlScience Thank you very much! I am trying to make cheaper ingredients for Tollens reagent to mirror a glass. I need a semi-transparent mirror for my project, but it's very hard to get. 1 company that sells mirroring chemicals is angelgilding, but they are so expensive. And silver nitrate is annoyingly expensive. Also flinnsci uses ammonium nitrate, which is also hard to get. Others use just ammonia, but I understood that it's really ammonia hydroxide. I bought that one as a cleaning chemicals, but no idea if it will work. So I wonder how to produce them.
I doubt cleaning ammonia will be concentrated enough. Usually it’s around 3-5%. You can get extra strength ammonia that’s around 10%, but even that might not be enough. Concentrated ammonia solution (25%) can be made by reacting ammonium sulfate and calcium hydroxide (both common fertilizers) and bubbling the ammonia gas into water.
@@RiehlScience "ammonia solution (25%) can be made by reacting ammonium sulfate and calcium hydroxide" Urea is a cheaper option & will decompose to Ammonia gas Around 135C.
@ Easier way to make Conc NHO3 is to use the same process, but just not add any water to the boiling flask. Using NH3NO3 would also work better than KNO3\NANO3. There are dozens of YT videos how to make conc. HNO3.
Beautiful and straightforward.
Classic demo, great vid! Also, isn’t it best practice to store acids and bases very far apart, rather than on the same shelf?

How many degrescelcius wlie the distillation
Azeotropic nitric acid boils at 121°C
Cool video. Hope you're staying safe!
Great video I'm surprised at the yield
I even discarded a little bit that came over first (not necessary). If you keep everything, the yield is close to 95%.
Why not add no water and distill over rfna?
Because fuming nitric acid is a pain to store and work with, so 68% is used whenever possible.
@@RiehlScience "Because fuming nitric acid is a pain to store and work with, so 68% is used whenever possible."
You can always dilute it for storage.
@ You can, but when distilling RFNA a ton of nitrogen dioxide is produced.
Now how bout u make WFNA and RFNA
Good idea!
I can buy nitric acid easier than sodium nitrate. Go figure.
That's a unique problem! Let me guess, they banned nitrates but not nitric acid?
@RiehlScience well you get a gold star! Lol! That's exactly why.
great video, seems way too easy to make a substance that makes most things explosive🤣🤣
Haha, yes! I'm thinking about making a video on perchloric acid, which is like nitric, but even stronger and more explosive!
Most compounds that rapidly decompose require much higher concentration of HNO3.
@@guytech7310 oh fair enough, would it be possible to boil off the water by creating a partial vacuum?
It might be possible to break the azeotrope at a different pressure, but it’s much easier to just not add the water and distill over pure nitric acid.

in China, owning pure nitrates is prohibited😢
That's too bad, nitrates have a lot of interesting chemistry. In the U.S. they're not illegal yet, but they have been getting harder to find.
State is a big enemy of the free citizens.
Like China has a terrorism problem. Maybe they should prohibit poor infrastructure construction. Now that would save many lives!
