Development of the Glass Electrode and the pH Response
The glass electrode is the most commonly used device to access the pH of an aqueous solution. It attains highly accurate measurements via simple and well-established procedures. However, the reasons why the glass electrode potential scales with hydrogen ion concentration according to almost Nernstian potential values have been long-standing challenges to explain. Only in the past 50 years has a...
متن کاملEquilibrium Potentials of Membrane Electrodes ( glass electrode / pH ) JUI
A simple thermodynamic theory of the equilibrium potentials of membrane electrodes is formulated and applied to the glass electrode for measurement of pH. The new formulation assumes the selective adsorption or binding of specific ions on the surface of the membrane which may or may not be permeable to the ion, and includes the conventional derivation based on reversible ion transport across me...

متن کاملThe Adsorption of H+ by Bacteria as Measured by the Glass Electrode.
Physiological studies on the behavior of bacteria in the presence of electrolytes have shown that there is a marked difference in the concentration of various ions affecting the viability and growth of bacteria (Winslow and Falk, 1923, and Winslow and Dolloff, 1928). Winslow and Upton (1926) in a study of the electrophoretic migration of vegetative cells, stated: "We are inclined to believe tha...
