pH testing only works with ionic, aqueous solutions (not that my chemistry is up to date or reliable...)
Otherwise, litmus papers would be all too easy!

^^This.

pH only has meaning if water is present. It's the potential for forming H+ ions and as far as I'm aware, it cannot occur without water.

I think that most well made bio ends up at just over 7.0 Probably the best way to get a ball park figure is to blank some IPA with a suitable indicator (something that changes at around 7) and see what happens, although I don't know what this really would tell us?
