A New Linear Equation Relating Interfacial Tension of Mercury and Isotension Potentials Describing Asymmetry in Electrocapillary Curves

Authors: Raji Heyrovska

It has been known for over a century that the interfacial tension of mercury dipping in electrolyte solutions changes with applied potential following a near parabolic course called the electrocapillary curve. Solution components adsorbable on mercury produce asymmetric curves with respect to the potential at the electrocapillary maximum. A simple mathematical description of this asymmetry has so far exercised and eluded many scientists. Here, the author shows a simple linear relation which describes the electrocapillary curves, using the existing data.

Comments: Pages. In Eqs. 3 and 4a, the last terms should read 1-R(+) and -52.01 resply.
