Quick question about mixture of HCl and nitrate salts


I have one question about mixing HCl and ammonium nitrate:

1) If I mix excess HCl with ammonium nitrate, I should get NH4Cl, HNO3 and HCl would be still left because it's in excess. That means NOCl and Cl2 would be generated.

2) If I mix excess NH4NO3 with HCl, there should be excess NH4NO3, NH4Cl and HNO3, so that means NOCl and Cl2 wouldn't be generated.

Now, is that true? If it is, I could use 2) mixture to oxidize sugar instead of using nitric acid. It should oxidize to oxalic acid which I could separate by neutralising the solution and then precipitating the calcium oxalate.

Are you trying for Aqua Regia or oxalic acid salts for dry distillation, or what?

I am trying to oxidize sugar without cjlorinating it using aqua regia.

You've lost me on the Aqua Regia!
68% HNO<sub>3</sub> should do it, I suppose!
Then again a long, strenuous bike ride would accomplish the same thing, in a manner of speaking?

Well, I don't have HNO3 so I want to make substitute.

To simplify my question:

If I would mix HCl with excess NH4NO3, would there be aqua regia formed or just HNO3 with excess nitrate and ammonium chloride?
Because I don't want NOCl and Cl2 in that solution.

It ultimately depends on stoiciometry. Try balancing the equation, and messing around with the moles.

HCl will not react completely to one side with a nitrate salt (unless it's silver, lead, or Hg(I) because those ppt). So any way you cut it, you'll make aqua regia.

If he used NaNO3 + HCl wouldn't some of the chloride ppt out as NaCl due to the common ion effect

I mixed 30% concentrated HCl solution with NH4NO3 and KNO3, there was no obvious reaction, but the mixture was able to slowly dissolve a copper pipe, with the generation of nitric oxides. Interestingly, although the solution was able to eventually completely dissolve the pipe after 24 hours, it did not seem to attack the plastic container it was in. Even after several days outside, the thin walled plastic water container did not rupture. The nitric oxides that were generated, however, corroded the inside of the plastic valve fitting and tubing that was inserted over the bottle.

Whether leaving a solution of 30% HCl and NH4NO3 to stand would eventually form oily droplets of dangerously sensitive NCl3, I do not know. I was only doing this as part of a different experiment.

For NCl<sub>3</sub> to form you'd need quite a large excess of HCl . . .

I'm not saying let's go kill all the stupid people...I'm just saying lets remove all the warning labels and let the problem sort itself out.
