the only thing that i can find to precipitate NaCl is use ethanol and "halocarbons and hydrocarbons" which barium azide is also insoluble in ethanol (and the latter is very vague) and to use HCl to precipitate the NaCl. bruh HCl with an azide would kill someone. this is extremely vague and if anyone knows how to do it pls share. no solvent that i can find from wiki on all 4 possible ionic compounds that it could form only precipitates the NaCl alone. here's the link to the wiki so you can see the section on the preparation:

i also haven't found any insoluble sodium salts that barium is soluble in that isn't an exotic compound

Search for a published procedure. The outlines you have presented, are inadequate.

You are newish. Talk to the guys that post in "Energetic Materials". They will endeavor to keep you alive.

You would have done better to keep this with your last thread for context.

What about adding barium hydroxide to hydrazine then adding isopropyl nitrite or similar?

Do you actually have a source of sodium azide?

Edit - I should also mention that this thread is well worth a read, it has a lot of really good information about azides and their precursors.

I was not planning on saying this but I will because I care for your health.

The way you are asking these questions leads me to believe you are not experienced in dealing with these substances , azides are nasty chemicals to deal with.
Sodium azide is a potent toxin as are many of its family members.
I 'recommended' a route via hydrazine, this too is not something to toy around with.

Perhaps it would be better if you get comfortable with a little more forgiving substances before revisiting the current subject.

Not trying to be an asshole here, just some well intended advice.

I see no reason to mince words here. Don't fuck around with this. If you don't understand salt solubility, you shouldn't be playing with azides. There are a variety of EM preparations ready-made for amateurs.

Sodium is the most difficult cation to precipitate in the amateur lab, because the standard method of precipitating sodium uses uranium, which is usually restricted. There are alternatives, particularly magnesium orotate, but the overall technique here requires some work.
