# What gives dilute/conc nitric acid/ conc sulfuric acid their oxidizing property?

I know that dilute sulfuric acid and very dilute nitric acid don't have any oxidizing tendency while dilute/conc $$\ce{HNO3}$$ and conc $$\ce{H2SO4}$$ do.

Why do these more concentrated acids have this property?

• Nilay, The question is interesting- none of the so-called answers in the links are true answers. Yes, there is a lot of hand waving there. Electrode potentials do not apply to conc. acid, so they better not be invoked here. I don't know the answer either. Aug 20 at 4:16
• Oh, and this here post is supposed to be for some "canonical answer"? And why it shouldn't go to the earlier question? Well, then at least clean up this "oxidizing property" which is hardly a good wording. Aug 20 at 15:07
