“I have received the greatest honor in my life - and the greatest surprise. Never did I dream that the Nobel Prize could be awarded for the reciprocal relations.”

“The thermodynamic properties of electrolyte solutions can be determined from the measurements of the voltage between electrodes reversible to both ions.”

“Estimates of the ionic mobilities vary over a considerable range; but in any event, the positive ionic defect is much more mobile in the solid than in the liquid, and its mobility varies very little with the temperature.”
