Alkali Flasks vs A Green Dragon

So without going into the bull that involves my GM throwing an effectively CR 33 green dragon at a 5th level character and a hundred and fifty commoners, I'm curious to know a few things:

-Does an Alkali Flask bypass the Acid Immunity of a dragon immune to Acid?
-Does an Alkali Flask inflict double damage on a Green/Black Dragon for it bein an "acid-based creature"?

1. It does not.
2. It will not.

You and I know that pH is a scale and the reason that bases burn flesh are different than the reason acids burn flesh. But in PF terms, acid damage is acid damage, even when it's not acid that does the damage.
