Hi i have been trying to make nitric acid, and i have some questions to make sure it really is nitric acid i have made.

 

here is what i did. Put 80 grams ammonium nitrate, 37 grams of copper, 50ml water and 100ml HCL into flask with a stopper and a tube in it so i could bubble NO2

into 50 ml of cold 3% H2O2. after i heated the flask by putting it into hot water it started bubbling.

 

It is strange to me the gas in the tube never looked brown or red like NO2, why is this?

 

also when it was finally done done bubbling i poured what i think should be nitric acid into a beaker, and it is bubbling like carbonated water, why? what is bubbling out?

 

So is this really nitric acid ?

i put some copper wire in it and it dissolved to a light blue solution so i do think its nitric acid.
