Individual Activity Coefficients of Ionic Species

摘要

The theoretical considerations which apply in particular for the temperature coefficient of the electric tension of the Pt-H2/H(+) electrode including those concerning the correction terms for the pressure of the hydrogen gas are first discussed, followed by the theoretical considerations needed for the computation of the ionic heats of transport 35C. The temperature coefficient of the electric tension of the Pt-H2/H(+) electrode was then measured using hydrochloric acid as electrolyte. The measurements agree with the theoretical expectations.
