In the following tutorial I show how to make white fuming nitric acid from cheap household products.

I believe that my product has a concentration of 95% or more, however it has a yellow tint due to nitrogen dioxide, which usually is not a problem for most applications. I read that the tint can easily be removed by bubbling air into the acid to push the nitrogen dioxide away.
My question is whether this operation would reduce the concentration of my product or not? Since low concentrated nitric acid can be produced by bubbling nitrogen dioxide into water, it seems that it is a good idea to keep the nitrogen dioxide in my product?

In commercial plants for producing high concentrated nitric acid (>90%) the condensed nitric acid (red fuming) is freed from NO2 with compressed air. If the used air is not dry enough the acid absorbs the humidity and gets diluted. A similar process is also used for weak nitric acid (
