how to get nitric acid

[The Rightest]

Nitric acid is used very commonly in explosives, like the uran bomb.
This is only an idea but the nitric acid being made of water and nitrous oxide(found in car exaust and hence acid rain) could be made by putting small amounts of water in a balloon and attaching it to the tail pipe of a car and turning it on. The fumes would mix with the water and thus make nitric acid.
I am not exactly shure about this so don't try it unless you know what your doing. If you feel more could be added to this feel free to post stuff here.

Car exhaust also contains carbon dioxide, correct? CO2 would react with water to make carbonic acid. Unless you can somehow filter the Nitrous Oxide from other gases, or Nitric Acid from the other acids in solution, I would not consider this worthwhile.

Roguesci.org has a forum dedicated to the amateur manufacture of nitric acid. Its worth checking out. The simplest method I have seen requires only basic glassware and a bubbler, makeshift or otherwise. I'm not sure if a ghetto bubbler would be effective of efficient but I know it would get you at least near decent results.

yes... you might indd get a nitric acid solution of 0,01%.. Do this a milion times, shake well and you'll have some reasonable acid, lol

[crazy white guy]

That's why I suggest the appropriate lab ware instead of a niggersynth.

I think methods other then distilling sulfuric with nitrate salts are a bit far fetched though. If you can manage that you got to be one hell of a good improvised kitchen explosive technician or indd stuff your house with lab equip. If anyone happens to be interested in it, i probably got an alternative nitric acid synth description back at my parrents place. Notify me if there is any interest and i'll put it up..

I'm curious to see what else is out there, please do put it up

You could try and steal the stuff from schools/universities. Last Friday in my chem. class we did a lab involving nitric acid, the teacher said the concentration was 60%, ever since then I've been wondering how good the security is in the school....
that might be too unrealistic though, we'll see.

But anyway, X-ray you should definitely post that synth.

This is a method that works.

YouTube - MAKING NITRIC ACID

Nothing fancy.

Just a thought on the original post... if you did indeed get nitric acid from the exhaust it would destroy the balloon in a hurry. Not great.

I think your theory is incorrect from the very start.

First, you are thinking of nitrogen dioxide (NO2), not nitrous oxide (N2O).
N2O is commonly known as laughing gas, is colourless, and can be pretty fun.
NO2 is a heavy brown gas, and would cause you some very painful problems if you huffed a balloon full of that.
I'm not even sure if these are by-products of modern fuels.

Second, Acid rain is more attributed due to the creation of sulphuric acid (H2SO4) from heavy concentrations of sulpherous gases ( just checked wiki. Sulphur dioxide. Gives a must less bumbly account of it all).

Also, modern engines and fuels burn cleaner, so the likelihood of these gases in abundance is reduced.

Allright i'll copy it as i find it in the text. However, it might refer to some other synths that are not posted now but you'll get the idea:

Synthetic nitric acid:
With the use of the same aparatus with which one can make sulfuric acid, one can produce nitric acid too (the picture looks like 2 bottles, connected both to a wash-flask which then both have an exit tube, these 2 exit tubes then meet eachoter in 1 big tube under which a bunsen burner stands. This big tube is lead through an end flask with distilled water (that will be turned into nitric). This can be done by the oxidation of ammoniak (gas). To do this you'll need a ammoniak developer and a gasometer (god knows wtf that is, probably a container that regulates outflow presure in which you can mix gasses) which you'll fill with 2 parts air and 1 part oxygen. The ammoniak gas is lead through a wash-flask with a strong potassium-hydroxide solution and the oxygen-air mix is lead through a concentrated sulfuric acid mix (in the wash bottle ofcourse). By flowing both gas mixtures through wash-bottles you can re-check the speed the mixtures flow by looking at the bubbles. In the big tube that connects both gas outlets you'll need a catalyst which is a little lump of platinated asbest that is heated by the bunsen burner.

At the start of this experiment you'll begin by letting the air-oxygen mix flow through the big tube (of btw heat resistant glass that wont melt) with the asbest in it. Continue this flow and add start adding the ammoniak gas too. The ratio should be 5 times as much oxygen air mix as ammoniak gass. Now start heating the big tube/catalyst with the burner to approx. 400 degrees celsius. As soon as this temperature is reached you'll see the catalyst glow at which the ammoniak will be turned with oxygen into nitric-oxydes. This reaction will create a lot of heat. The tube will now fill with brown gasses which are lead into the big flask filled with a bit of water (does not say quantities). By shaking this flask in which the gasses are flowing you are creating a low concentration nitric acid solution.


My sidenotes:
A. this is incredibly difficult
B. try to get platinated asbest, lol
C. find yourself a gasometer
D. the concentration of the nitric will be damn low
E. i think this synth is for curiousity reasons only, lol.

...Holy crap. Ammonia burner for nitric acid production. We should pool some resources and have the most able and qualified person set this bad chicken up.. then start the jug'a'month club!! Four liters, four months, forty bucks!! ...Mmmm I want.
