Make Nitric Acid without Sulfuric Acid by Oxalate Precipitation

NurdRage - 2024-07-14

In this video we make nitric acid by reacting calcium nitrate with oxalic acid.

The process is rather simple, dissolve 300g of Calcium Ammonium Nitrate (A common fertilizer) in 1L of water and then dissolve 150g of Oxalic Acid dihydrate in 300mL of water with heating. Then mix the two. A white precipitate of calcium oxalate is formed. Filter this off and distill the filtrate. The distillate will be dilute nitric acid. Fractionally distill that to get azeotropic nitric acid. The yield is around 74%

Hi Nurd.Funny that you posted today as just made Nitric with calcium nitrate and sodium Bisulfate (Pool supply).Looks like it worked.Just waiting for it to cool off and then will test.Thanks for your help again.

Absolutely love these short but well described videos on the process. Thank you master!

@SolarSeeker45 - 2024-12-17

So far my favorite method so far is distillation from calcium ammonium nitrate with sulfuric acid and a minimal amount of water. The calcium sulfate washes out decently well with water and very easily with hydrochloric acid. I've also been looking into platinum bright embers for gas logs. Because of the platinum content they can be used as a catalyst bed making the Ostwald process readily accessible to the amateur chemist.

Great video! I always love learning new pathways to get useful reagents, and this presentation is another outstanding example!
I look forward to trying this for the experience! Thank you!

@chembydesign - 2025-03-19

Of all the methods you spoke of on your channel I like this one best because it allows me to make the dilute acid without poisoning myslf with nitrogen dioxide. Unlike many of you, I do not have a fume hood, and if I did it would have to be a ductless fume hood because I live in a heavily populated city.

Calcium oxalate is what kidney stones are made of 😱

@idontknowmyfirstname69 - 2025-05-22

Getting the filtrate separated from calcium sulfate is easy.... First let it settle for like an hour. Then take a cotton ball and jam it into the neck of a funnel. Decant just the liquid into the funnel and collect the filtrate. This filters like regular filter paper but it also filters by allowing just the liquid to wick down the fibers of the cotton ball. Filters quick and clean

@y33t23 - 2024-07-14

Interesting method. Since I can get 25kg of Sodium Bisulfate for 42,99€ with free shipping, I'll stick to that method if I need nitric acid.
As a bonus on top of better cost effectiveness, you get fuming nitric acid directly, which is always easier to dilute to regular nitric acid than the other way around.

@mookinbabysealfurmittens - 2024-08-28

5:27 He discusses oxalic acid versus sodium bisulfate. I'm not arguing (even he said he'll stick to using sodium bisulfate). I'm just noting the specific point where he notes some pros & cons of each.

@KugelFits - 2025-03-22

Where do you get that at that price?

@SuperAngelofglory - 2024-11-24

Fortunately, in my country you can actually find azeotropic nitric acid on the Internet to buy. It is sold as limescale remover for aluminium pipes. Costs 10 dollars for a 5 kg/3.5 litres jug.

@till2911 - 2024-07-14

use nitric acid to make oxalic acid to make nitric acid. (that might even be a good option cause while making oxalic acid NitrogenDioxide forms and you can win your nitric acid back).

@NurdRage - 2024-07-14

not a bad idea, but i worry about losses. The process for making oxalic acid and nitric acid isn't perfectly high yielding. So you may end up with less than what you started with. But worth experimenting with if you have a good gas capture setup.

Nice. Now I need a video to synthesis oxalic acid. Sadly in the UK, oxalic acid is a regulated poison and you need an EPP licence to get it over 10% concentration.

Yowch! this is a shot in the dark, but if you eat a lot of Spinach, maybe try cutting back on that. Spinach is famously high in Oxalic Acid and is number one on the things kidney stone patients aren't recommended to eat (among other greens)

@kaboom4679 - 2024-07-15

How about a Pauling furnace ?
Sure it is inefficient , and while it would still require workup of the product , just like any nitrate salt route , it can run continuously instead of just doing batches with relatively spendy ingredients , filtering , etc ..
The beauty of this and electrchem in general , is you do not need grid power .
An off grid solar setup can easily be used for a dedicated lab not directly subjected to the whims and fortunes of the local power company .

@Preyhawk81 - 2024-07-19

My idea too.

@林昀陞-l2x - 2024-07-14

You should try copper nitrate waste version too,😃😃
probably easier than electrolysis method

@NurdRage - 2024-07-14

probably, but considering copper oxalate is extremely difficult to filter, it might be an issue. I'll see what i can do.
