Hey, chemists!

How would you describe the smell of acid? Does it have a smell? (Any kind of acid will do; I'm looking for commonalities here.)

I'd strongly advise against bitter, because bitter is what we taste for bases - compare caffeine (bitter) to lemons (sharp, acrid) and vinegar (acrid, sour). As others have said though, acids smell of themselves, basically, and aside from sour, they'll all be fairly distinctive, especially to someone with a more refined nose.

That said, many common acids are also found in nature, so citric acid has fruity overtones as does malic, hydrochloric acid gives the sharp stink of vomit (in part), prussic acid smells like almonds and so on. Hydrofluoric acid smells like oh-shit-my-bones-are-melting.

He's smelling an acid that doesn't exist in reality, that he doesn't initially recognize as an acid. I'll probably go with either "sour" or "sharp" as the initial descriptor, or both.
