Btw, would nitric acid and hydroiodic acid being even stronger then
aqua regia? Is there any acid that can dissolve iridium, since I've
heard that iridium withstands aqua regia.
Thanks
A mixture of nitric and sulfuric acids is used in nitration
reactions. Nitration of organic chemicals by nitric acid
produces water as a by-product. Sulfuric acid acts as a
catalyst, and it absorbs the water, pulling the reaction to
completion.
For more details, Google "nitration reaction", or go to
http://en.wikipedia.org/wiki/Nitration
Concentrated sulfuric acid will suck the water out of anything, so
when it's added to nitric acid, it dehydrates it to an energetic ion
(I forget which; look it up) that attacks organic compounds, forming
nitro groups. Nitration of cotton or glycerine makes explosives, etc.

It forms the [NO2]+ cation.
No, because nitric acid will react with hydroiodic acid to give iodine
and either NO or NO2. Not useful.
So, would HNO3 + HI dissolve gold? I guess not.
H2SO4 + 4HClO4 -> Cl2O7?
Is NH4IO4 a more powerful oxidizer then NH4ClO4?
