I can't wait for the journal so I took a quick trip to a dictionary
that has some limited etimology (

        Main Entry: pH
        Pronunciation: 'pE-'Ach
        Function: noun
        Etymology: German, from _Potenz_ power + H 
        Date: 1909

"Power" actually does make sense (as opposed to pons).
