Doubts and Comments about the Origin of pH-Glass Electrode Potential

Abstract

Dole assumed first that pH-glass electrode is semipermeable only to hydrogen ions. However, Hammond disproved Dole's assumption by his experiment. The recent theories for pH-glass electrode generally accepted so far have been based on the assumption that hydrogen ions do not cross the glass. Some doubts and comments are presented to the theories from our viewpoint that is based on the high mobility of hydrogen ion in the pH-glass electrode.
