I'd go with one of acrid; pungent; sharp; or bitter.
Most acids don't actually smell of anything. If an acid is strong enough to smell, it will normally be highly unpleasant, as what it'll be doing is dissolving into the liquid in your nose and, well, turning it into the acid you're smelling... and you don't want acid up your nose.
