An electrochemical viewpoint on the solubility of silver halides in water

Autor: Zdeněk Samec, Takashi Kakiuchi

Publikováno v: Journal of Solid State Electrochemistry. 24:3185-3189

An electrochemical view on the solubility product of sparingly soluble salts in water, which Nernst introduced in 1892, is helpful for better understanding of the precipitation equilibria. Specifically exemplified is the solubility of silver halides

Single-ion activity: a nonthermodynamically measurable quantity

Autor: Takashi Kakiuchi

Publikováno v: Journal of Solid State Electrochemistry. 24:2093-2095

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,
