Nitrates are used in explosives. So, it's unlikely you'll
find a source of nitric acid.

I need some nitric acid to passivate some stainless. Anybody
know of a
common local source? I see my favorite McMaster Carr don't
have it.

For example, you cab buy hydrochloric acid as muratic acid
at any hardware
store. or phosphoric acid as "Lime Away" at any farm and
fleet store or
sulfuric acid as battery acid at any auto parts store.

I see citric acid is also use to passivate. Know a local
source for this?
