Nitric Acid Questions
I know there are many threads on the production of nitric acid, http://www.sciencemadness.org/talk/viewthread.php?tid=13090 and many disagree with each other so here is my question, what is the product when
distilling a potassium nitrate for example and sulfuric acid. Lot's of threads give the equation of KNO3 + H2SO4 --> HNO3 + KHSO4, but wouldn't
this reaction work with half the amount of sulfuric acid by the following equation KHSO4 + KNO3 --> HNO3 + K2SO4. Also, I have read that adding
aluminum metal rids the solution of dissolved nitrogen oxides, what does this reaction proceed by. Doesn't this contaminate the solution with
aluminum salts?

It does work but conversion is slow and higher temp.s are required, leading to a much increased decomp. rate of NHO3!

Does anyone know of any other way to remove the dissolved nitrogen oxides from solution. I have also read on this site that simply leaving the HNO3
in open air will let them dissipate, but won't this dilute the acid due to the volatility of HNO3?
