Sodium nitrate and HCl issue

[Exotic_chew]

Hi there ,

Been trying to make some nitric acid with sodium nitrate.
But there is the problem, whenever I add HCl to sodium nitrate it bubbles and foams out of the beaker.

I'm suspecting my so called sodium nitrate is something else.

Can anyone guide me on it?

Also is there a way to extract nitric acid from sodium nitrate and hcl mix?

Thank you

Poormans Nitric is what your looking for. It uses sulfuric acid and a nitrate salt, most commonly sodium nitrate, but potassium nitrate works as well.

HCl and sodium nitrate makes Poormans AR.

These will give you guidance.

The recipe I was given and use is for 1 cup of sodium nitrate dissolved in water
for an hour then you add one quart of H2SO4 and let it sit overnight. Pour off
the clear liquid leaving behind any undissolved sodium nitrate.
