what metals do not react with concentrated nitric acid at all?
any help is appreciated  Comment viewing options     But note...
if you mix concentrated nitric acid and concentrated sulphuric
acid together to get a solution called "aqua regia", it can
react with all metals.  No! 3 parts HNO[sub]3[/sub] and 1 part
HCl is aqua regia; it works because it produces free chlorine in
an oxiding environment. The chlorine attacks the Au or the Pt,
both of which are rather more reactive than people realize. A
mixture of HNO[sub]3[/sub] (the red lion) and
H[sub]2[/sub]SO[sub]4[/sub] (oil of vitriol) has no special name
as far as I know.  Ah yer right. Sorry for giving the incorrect
chemicals in the last post.  Yes, and neither Ir nor Os is
attacked by aqua regia  But they're attacked by something else
Yes. molten NaHSO[sub]4[/sub]   WebElements: the periodic table
