hi guys,
first i have to say -as new born member- a big hello to your great board.
so now:
i want to distill HNO3 from a KNO3 and H2SO4 solution.
a) would car-battery conc. of H2SO4 (~65%)work ?
b) i read in an serious "making of nitric acid" that u should add some AgNO3. anybody heard about this ?

You need 98% to get pure nitric acid, but you could just boil the acid you have until very thick fumes come off to concentrate it.
65% will make nitric acid I think, but it will have quite a lot of moisture in it.
I don't know about silver nitrate. it'll probably cost too much to be worth it.
