what metals do not react with concentrated nitric acid at all? any help is appreciated
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]
