Abstract

This paper describes a simple operational relationship between the drop-time of a dropping mercury electrode and the interfacial tension at a charged mercury/aqueous solution interface. An apparatus and technique for measuring drop-times is reported, and examples are given of the fit of experimental drop-times to literature values of interfacial tensions. The operational relationship is independent of temperature in the range 293-313 K.
