Single-ion activity: a nonthermodynamically measurable quantity

Abstract

Ionic liquid salt bridge (ILSB) that effectively minimizes the liquid junction potential in a galvanic cell articulates the nonthermodynamic measurability of single-ion activity. Points for further improvement of the stability of ILSB are summarized, and associated intriguing phenomena at the ILSB-W interface are described.
