Mix it with some nitric acid and you've got yourself some barium nitrate which is pretty usefull (Strobe stars, glitters, silver stars...)

Just a problem.....I don't have anymore HNO3(i got mine from my highschool'laboratory and i can't get anymore),but I will make some from H2SO4 and KNO3.

Mix it with some NH4(NO3)2 an you've got barium nitrate too.


BaOH + NH4(NO3)2 --> Ba(NO3)2 + NH3 + H2O

I did think about that but I have to do it out side because de NH3 smels very bad.Thanks for the idea.

If I'm not wholly incorrect, Ammonium Nitrate is NH4NO3 not NH4(NO3)2, hence, that reaction would need re-balancing.

Yes you are right.The corect formula is NH4NO3 and the barium hydroxide is Ba(OH)2.

Oh, and the reaction is :


Ba(OH)2 +2NH4NO3 ->Ba(NO3)2 +2NH3 +2H2O

So work on your chemestry:).

OMG..It's not working.I calculated the reaction and how much amount of NH4NO3 I needed and the reaction doesn't work.In most reactions of a hydroxide(NaOH) and NH4NO3 I get a clear solution that recristalizes easy.But when I mixt the two the Barium hydroxide stays on the botom and doesn't react.I think I'm trow and forget about it.In Romania you can't store any reactants and you don;t have were to buy them and even if you have they are to expensive.

It's due to the insolubility of the hydroxide. Try boiling the solution.

Good luck, do report back when you find a practical method.

Anyway, Conc Sulphuric acid is just as hard to get hold of as conc Nitric acid. You can buy conc Nitric Acid for about £4/Litre.


Dissolving Barium Hydroxide in dilute Nitric Acid is the best way of making Barium Nitrate. See the BaCO3 to Ba(NO3)2 thread because the method discussed is exactly the same.

nice :)
