Ammonium nitrate + HCl

Alastair - 9-10-2011 at 08:23

NH4NO3 + HCl ---> NH4Cl + HNO3 (with water and some excess HCl)

I wanted to ask if there was any practical (or theoretical) way of seperating the two products?

I need HNO3 to react with a metal for NO generation and i want to obtain NH4Cl too.

Thank You for responses.

No is the short answer!
Nitrosyl chloride (NOCl), toxic and irritant, will be driven off on heating the mixture!
-On the plus side, you will have 'Aqua Regia' . . .

For all attempting to make acids out of HCl solutions use H2SO4, I have never gained any good acids using HCl even in attempts to make AcOH out of NaOAc and HCl, the equilibrium just sucks to much and the water is just to bulky to make anything of value.

Seems i should have put this thread in ''endings'' not ''beginnings'' :D

Alright, then if some person would add Fe or Cu metal into that ion salad and maybe lead (hopefully) evolving gas through a water chamber to disolve NH3, would the obtained produst be solely NO (and some NO2)?
Answers in Sciencemadness make me very unconfident about my chemistry knowledge :D

I can't see NOX being evolved by your mixture; furthermore, ammonia is displaced from its salts only by strong bases!
NO, by the way, is oxidised to NO<sub>2</sub> on contact with atmospheric oxygen!

Yea, i know. Need NO/NO2.

Why not add HCL(aq) to sodium nitrite?

"attempted to make KNO2 by thermal decomposition in the past."

"Adding a bit of this to water and tossing in a splash of HCl, I was rewarded with bubbling and thick orange-red fumes."~ http://www.sciencemadness.org/talk/viewthread.php?tid=52#pid...

Sodium nitrite 2 pounds for $10!

I once made NOx with HCl and NaNO<sub>2</sub> and I think that nitrosyl chloride gas formed when excess conc. acid was added to the solution (very pungent, strange smell which was not HCl). It might be a better idea to use sulfuric acid instead.

Sorry I couldnt respond for a while. It is impossible to get anything-NO2 in my country ;D Anyway thank you for responses!

"The ingredients of the product are: Sodium Chloride (NaCl) 99.26%, Sodium Nitrite (NaNO2) 0.74%" :(

In any case, if you need a license to buy NaNO2 in Alastair's place, customs may not be amused. OTOH, I wonder how "Free movement of goods" in the EU and different regulations concerning chemicals and drugs work out?

All ebay jokes aside, I've bought stuff from quartzpegmatite (the link hissingnoise gave) before and whoever is behind the name knows what they're doing. DudaDiesel has started selling on ebay as well, with some decent prices. Quartzpegmatite is just a repacker, but if you shoot them an email they'll work with you on packaging and unlisted items.
